Grout renovation for bathrooms and showers
Dark silicone joints on the bathtub, tile grout that no longer comes clean: we renew both as a standalone service, even if nothing else is being done in the bathroom. We regrout the tiles using a thin-bed method, without scraping out the old grout. We also remove and treat any mould in the grout. In most cases, we finish within a day.
AT A GLANCE
We usually renew silicone and tile grout within a day, with tile grout being refreshed without scraping out the old joints. Mould in the grout is removed and treated during the process. The cost is typically between €350 and €900, with a fixed price provided after inspection.

WE UNDERSTAND YOUR CONCERNS
We do. bazuba renews silicone and tile grout as a dedicated service, even if nothing else is being done in your bathroom. You will receive a fixed appointment, a dedicated contact person, and a fixed price after the inspection.
Not for tile grout. We use the thin-bed method, applying the new grout over the old, in almost the same colour. Silicone joints, however, are always completely removed and replaced, as nothing else will last.
Only if the cause remains. We remove the old silicone joint along with any mould underneath and treat the affected areas before applying the new joint. Afterwards, it helps to ventilate after showering and wipe the corners dry. If the mould still returns, there is usually a leak behind it, which we can identify during the inspection.
The joint is the weak point in the bathroom. If it is leaking, water seeps behind the bath or tiles, turning a small job into water damage. The renovation itself usually takes a day.
TAILORED TO YOUR BATHROOM
Classic
The old joint is completely removed, the surface is cleaned, and then we apply a new one. Any mould underneath is removed as well.
Guide to silicone joints
Without scraping out
With the thin-bed method, the new grout is applied over the old one, in almost the same colour. This allows you to renew just one area without it being noticeable.
How the thin-bed method works
Hygiene
Black spots in silicone cannot be wiped away, as the fungus is inside the material. We remove the mould, treat the area, and apply a new joint. We will also tell you where the moisture is coming from.

250+ colours
If you no longer like your tiles: we coat them in your chosen colour, with an 8-year guarantee on the coating.
More about tile coatingTHE DIFFERENCE
There are two ways to renew tile grout. The traditional method removes the old grout. Instead, we use the thin-bed method: the new grout is applied directly onto the existing one.
| Scraping out grout | bazuba Thin-bed method | |
|---|---|---|
| Procedure | Old grout is milled or scraped out | New grout is applied onto the existing one |
| Dust | Milling creates dust throughout the bathroom | Hardly any dust, the bathroom remains usable |
| Tile edges | Can be slightly damaged during milling | Remain untouched |
| Appearance | The new grout often differs visibly | Almost identical colour, even for partial areas |
| Duration | Longer, as scraping and drying are required | Usually one day |
| Price | Difficult to estimate in advance | Fixed price after inspection |
Silicone joints are completely removed and replaced in both cases. The thin-bed method applies to the tile grout.
CUSTOMER REVIEWS
„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."

The planning concept was implemented 100% in reality and at what we think is a really fair price. No trouble with the craftsmen at all—in fact, 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"

FREQUENT QUESTIONS
This is done by specialist bathroom renovation companies. At bazuba, grout renovation is a separate service: We will come even if nothing else is being done in the bathroom. You will receive a fixed appointment, a dedicated contact person, and a fixed price after the inspection. Using the form on this page, your enquiry will be sent to the bazuba company in your region.
Yes. We use the thin-bed method: The new grout is applied over the existing one, instead of removing the old grout. Colour and appearance can be matched so that they closely resemble the existing grout. This protects the tile edges, creates hardly any dust, and allows you to renew just one area, such as the shower.
This depends on how many metres of grout need to be renewed, whether it concerns silicone or tile joints, and the condition of the substrate. As a guideline: wall joints usually cost between €350 and €900, floor joints between €250 and €600. After the free inspection, you will receive a fixed price, no hidden costs.
You can find more figures, examples by bathroom size, and our price calculator in the guide. Bathroom renovation costs.
Usually one day. Larger bathrooms or badly damaged grout may take longer; we will let you know after the inspection. Fresh silicone then needs around 24 hours to fully cure. The joint should remain dry during this time.
Depending on use and care, about five to ten years. In the shower, they age faster than at the washbasin because they get wet every day. If the silicone becomes brittle, dark, or starts to come away at the edges, it’s time for a new joint before water gets behind it.
For silicone joints, only replacement provides a lasting solution, as mould penetrates the material and cleaners merely bleach it. We therefore remove the affected joint, treat the area against mould, and then apply a new one. Tile grout can often be cleaned, but if it is washed out or cracked, renewal is advisable. Here too, we treat affected areas before applying new grout. Afterwards, remember: ventilate after showering and wipe corners dry. Learn more in our guide. Remove mould in the bathroom.
Yes, and that’s exactly what the thin-bed method is for. Because the colour of the new tile grout can be matched to the existing one, the renewed area does not stand out. We completely replace the silicone joints in the shower.
Old tiles get a new surface in the colour of your choice, with over 250 colours available.
Waterproof and completely seamless, applied directly onto the existing tiles.
Large, waterproof panels with minimal joints, in wood, concrete, or stone effect.
Send us a photo of your grout and we will advise you on the best solution. No obligation and no pressure.
