How long does a bathroom renovation take?

A classic bathroom renovation with demolition usually takes 2 to 4 weeks, and even longer with drying times. Without demolition, it is significantly faster: a bathtub can be newly coated in one day, and a level-access shower instead of the tub is ready in 2 to 3 days.

Here you will find out how long each job takes, what can extend a renovation, and how long you will be unable to use your bathroom.

Indicative times for on-site work, depending on the bathroom and the company. We will provide the exact schedule after the free inspection. As of: 23 September 2026. Checked by Julien El-Bahy (bazuba headquarters).

How long does each job in the bathroom take?

With bazuba, the tiles remain on the wall and the bathtub often stays in place. There is no demolition, no new screed that needs to dry, and no switching between multiple trades. That is why most jobs take hours or a few days instead of weeks.

This is how long a classic bathroom renovation takes, phase by phase

In a classic renovation, the bathroom is stripped back to the shell and rebuilt. The work is carried out one after the other, as each trade waits for the previous one to finish. For a medium-sized bathroom, this usually takes 2 to 4 weeks. These are typical ranges; each company plans differently.

PhaseTypical durationWhat happens
Demolition1 to 3 daysTiles, bathtub, toilet and washbasin removed, debris disposed of
Installation2 to 4 daysnew water and wastewater pipes, electrics
Screed and plastera few days to several weeksnew cement screed must dry for a long time depending on thickness, quick-drying screed only a few days
Sealing1 to 2 daysSeal shower and splash areas, allow to dry
Tilingbazuba does not offer this3 to 5 daysLay tiles, grout, allow to cure
Assembly and completion1 to 3 daysShower, toilet, washbasin, fittings, silicone joints, final cleaning

Typical timeframes for a classic renovation with demolition. Small bathrooms are quicker, large bathrooms and old pipes take longer.

Why it is faster without demolition

The lengthy items in the table are eliminated without demolition: there is no rubble, no new screed that needs to dry, and no tiling work, as the existing tiles are either coated or covered with panels. Instead of four different trades, a single team usually handles the project from start to finish. Where pipes need to be laid, for example in Tub out, shower in, it takes a few days, but not weeks.

What can extend a bathroom renovation

  • Drying times: New screed and plaster require, depending on the material, several days to weeks before tiling can begin.
  • Old pipes: If water or wastewater pipes are damaged, additional days may be needed, sometimes including work in adjacent rooms.
  • Surprises behind the tiles: Damp walls, mould, or previous water damage often only become apparent during demolition.
  • Delivery times: Tiles, shower screens, or custom-made furniture often have delivery times of several weeks. Please plan your order early.
  • Multiple tradespeople: If the tiler has to wait for the plumber, gaps may occur in the schedule.
  • Rented flats and owners’ associations: Approval from the landlord or property management and observing quiet hours in the building should be included in your schedule. More information at Bathroom renovation in a rented flat.

How long will you be unable to use your bathroom?

With a classic renovation, the bathroom cannot be used for the entire construction period, usually two to four weeks. If you only have one bathroom, you will need an alternative for this time, such as a second bathroom or WC in the house or family nearby.

Without demolition, the interruption is short. You can use a coated bathtub again after 24 hours, after installing a bathtub door you can bathe the next day, and after slip resistance treatment you can shower immediately. With Tub out, shower in, the bathroom is restricted for the 2 to 3 days of the work. We will clarify what remains usable during this time at the inspection.

How long will it take for your bathroom?,We will inspect your bathroom free of charge and then provide you with the duration and a fixed price.

A classic renovation is the right choice if all pipes need to be replaced, the layout is changing, or you want completely new tiles. If the base is in good condition and it is mainly the appearance or the high bathtub rim that bothers you, it is faster and more cost-effective without demolition.

Frequently asked questions about the duration of a bathroom renovation

A classic bathroom renovation with demolition usually takes 2 to 4 weeks for a medium-sized bathroom, and even longer with long drying times. Without demolition, it is significantly faster: a bathtub is coated in one day, a shower instead of the tub is ready in 2 to 3 days, and a whole bathroom is usually finished in a few days.

With demolition and new tiles, usually 2 to 4 weeks; for large bathrooms or old pipes, it can take longer. Without demolition, the ECO-Bad is ready from 3 days, and the seamless bathroom from 5 days, depending on the scope.

There is no fixed limit. It is important that you agree a schedule with a start and completion date in writing before placing the order. For a classic renovation of a medium-sized bathroom, 2 to 4 weeks is usual; if it takes significantly longer, the company should be able to justify this, for example due to drying times or delivery delays.

Tiling itself usually takes 3 to 5 days in a medium-sized bathroom, plus sealing and drying of the substrate. bazuba does not lay tiles: we coat the existing tiles in a new colour, which usually takes around 2 days.

With a classic renovation, the entire construction period, usually 2 to 4 weeks. Without demolition, the interruption is short: a coated bathtub is usable again after 24 hours, and after installing a bathtub door you can bathe the next day.

With us, usually 2 to 3 days. The bathtub is removed, the connections are adapted, and a flat shower is installed, while the walls remain.

For a classic renovation, you should allow several weeks to months, as tradespeople are often fully booked and tiles and sanitary fittings have delivery times. Without demolition, the lead time is usually shorter: after the inspection and the quote, we arrange an appointment, and the company in your area will tell you the current waiting time.

Yes, in most cases. For a classic renovation, you will need an alternative for shower and WC for several weeks. Without demolition, the work takes hours to a few days, and there is little dust and no construction debris.

„On the recommendation of a friend, we got in touch with bazuba Rostock for our bathroom renovation. Since it’s a rental apartment, there were quite a few things to consider with the landlord/owner’s approval, but we were able to implement many individual wishes at our own expense. The initial contact was very pleasant, and first, an assessment was made, and of course, the initial ideas and wishes for the project were recorded. The basic task was to transform the over 20-year-old tiled bathroom with an old bathtub into a modern seamless bathroom with a walk-in rain shower. The company’s showroom had quite a few displays, where we could get our first personal impressions. Then we put together the rest from the catalogs, and we also relied on the advice and recommendations of the boss there, who contributed some great ideas. Then we received an offer with a 3D visualization of the finished bathroom. This allowed us to work very well together with the owner and bazuba on the details and arrive at a final result. The correspondence between bazuba and the owner also went very smoothly, and we were very well informed about delivery times, construction times, and the entire process up to the finished bathroom. We helped set up the construction site by covering the floor and cabinets, and the company’s employees were very friendly and informative about the work steps. We hardly had to ask anything because every morning we were informed about what would happen that day until quitting time. The announced construction time was even undercut by 2 days because everything really fit together, and the trades worked hand in hand. The handover and the finished result, including explanations of all the components, care instructions, and warranties, worked wonderfully and were presented to us very transparently. All in all, we are very satisfied with the result, and for the small space available, it almost feels like being in a good hotel when you step into the shower in the morning 😉 I can definitely recommend bazuba Rostock and am happy to show some before-and-after pictures. It’s not decorated or furnished yet, but it’s about the raw result."

„Complete renovation of bathroom and WC — After weeks of searching online for a company that could take on our project (complete renovation of bathroom and WC), we came across bazuba. Although all customer reviews pointed to an outstanding company, we still felt the need to visit the company location in Guntramsdorf in person first. But from that moment on, it was clear to us that only this company was suitable for our project. The exceptionally warm, competent, polite, friendly, and patient team immediately convinced us. From then on, everything went very quickly. We arranged an inspection appointment with Mr. Weninger. The inspection, consultation, measuring, and addressing special requests all took place in a very friendly and relaxed atmosphere. The gentleman was very patient and really took a lot of time for us, only leaving once even the smallest detail was clarified. After the very detailed offer and placing the order, the renovation work began punctually on the agreed date. From here on, I have to keep it short, otherwise I would need two more pages. ALL involved, whether subcontractors or the truly outstanding bazuba specialists, carried out their tasks so competently, punctually, cleanly, almost dust-free, quickly, friendly, politely, courteously, professionally, precisely, and expertly that words almost fail me. The continuous support and (after)care of my project are also worth highlighting. After completing the very extensive work, I now have two real gems (bathroom and WC), and I find myself spending much more time there than really necessary. The conclusion of a highly satisfied and enthusiastic customer: the best 10-star company I have ever dealt with. I have recommended and will always recommend bazuba."

„Everything just fits perfectly! :o) — We had our roughly 50-year-old bathroom and the equally old toilet renovated by bazuba, and also had the shower in the second bathroom modernized. From the very first (phone) contact, we had a good feeling. Bathroom planner Raffael came to our home and went through the various measures with us, advising us well and being very patient. We were also able to discuss the price well with him, and in the end, he made us an offer that we were very happy with. We had also obtained quotes from competitors, which were significantly more expensive — we’re talking +50% and more. The implementation then went perfectly. First came the dismantling team, then the electricians, the plasterers/floor layers, and finally the assembly team. Overall, the work took almost three weeks, but that was agreed upon in advance and was therefore fine. All workers always arrived as scheduled, were very friendly, explained a lot to us, and did a great job. We were also very grateful that they pointed out some possible/necessary improvements to us. Spontaneous change requests on our part were received and implemented kindly. At the same time, planner Raffael and project manager Anel were always reachable for us and responded quickly to our questions. The result speaks for itself: from old-fashioned, dark rooms with very worn installations, we now have friendly, modern wet rooms that you enjoy entering again. The planning concept was implemented 100% in reality and at what we believe is a really fair price. No hassle with the craftsmen, quite the opposite — it was a pleasure, and we can warmly recommend the entire bazuba team."

„Due to water damage in 2023 and subsequent repair work by a specialist company, we were then looking for a company to get our bathroom back in shape. This turned out to be not so easy; local companies either declined due to lack of time or didn’t show up despite appointments. Through internet research, we came across bazuba in Karlsruhe. We quickly had a first appointment with Mr. Glutsch. He arrived on time at our place, listened to our ideas about remodeling the bathroom, and shared his professional knowledge and comments. He took measurements, made notes, and promised to prepare an offer, which arrived in the shortest time. Due to several work appointments with bazuba, he already told us in advance that the work would be delayed and we should expect a date in March/April. But that didn’t matter to us in the end, since thanks to the preliminary work of the renovation company, we could still use our 30-year-old bathroom. When choosing the ceramics and the walk-in shower, we were with Mr. Glutsch at C.Ufer in KA (top advice!). In April, the work started on our partially renovated bathroom. After about 2 weeks, we could fully use our new bathroom; for the shower enclosure, we had to make do with a temporary solution, which was replaced after 5 weeks by a glass partition from Kermi. All in all, we were very impressed by the support and advice from bazuba (special thanks to Mr. Glutsch). A big compliment to the two skilled workers responsible for the work!! Without a doubt, 5 stars for bazuba."

„Good decision! — We chose BAZUBA because of a report on an online portal... and we have no regrets! Our wishes were discussed and planned in the showroom with an incredible amount of patience. Even changes and special requests before the renovation started were implemented quickly and easily. The entire construction team also deserves mention – everyone was without exception polite and friendly. I especially want to mention Mr. Robert, who brightened every one of our site visits with his good mood. In hindsight, we can now list the following reasons why we recommend BAZUBA to everyone: 1.) The price – All other quotes were about 25% higher than BAZUBA’s. 2.) The team – As already mentioned, patience and friendliness are top priorities here. 3.) The planning – None of our wishes were considered impossible. Even special requests were gladly fulfilled. 4.) The working time – A conventional renovation would have taken at least 4 weeks and the whole house would have been dusty. BAZUBA finished on schedule in 2 weeks. 5.) The quality – Nothing wobbles, nothing is scratched. The bathtub looks like new. The walls are flawless. Every joint fits perfectly. 6.) The look – We chose a seamless bathroom. Compared to tiles, our bathroom now feels much friendlier and warmer. 7.) The warranty! All in all, we are satisfied customers and would have our bathroom renovated by BAZUBA again anytime."

„Perfect! Absolutely recommend. — Tub out and shower in! From start to finish, we can only give the highest praise. The consultant, Mr. Raffael Weninger, gave us excellent advice at home. He took our needs into account and came up with a perfect plan for us with his great ideas. The craftsmen also deserve the highest praise. They were extremely careful to avoid dust and dirt, which is not easy with this kind of work. The first two days, two careful installers took on their responsible tasks. After all, all newly laid water pipes and drains have to be completely sealed. The third and fourth days belonged to the quick gentlemen Jànos and Gàbor, who were able to complete this partial renovation on time — without taking a break! It must be said that all "our" four craftsmen are extremely friendly and hardworking. Otherwise, our project would not have been completed perfectly in this relatively short time. On the third day, the company owner visited us, checked on the progress, and asked about our satisfaction so far. That builds trust. Now we enjoy our new shower pleasure every day! We gladly recommend this company with its great employees. Warm regards! Christian & Sylvia Karner"
