WE UNDERSTAND YOUR CONCERNS
Wheelchair accessible bathroom renovation: does the entire bathroom need to be removed? Honest answers
"Surely the whole bathroom has to go."
No. The bathtub door is fitted into your existing bathtub. And if the tub is replaced by a shower, the old wall tiles remain and are seamlessly covered. Only what you really need is renovated.
"Then my bathroom will look like a hospital."
It doesn't have to. A shower with a glass wall or a bathtub door that matches the colour of the tub does not look clinical. You choose the colours and fittings yourself, and we make sure everything remains safe.
"How long will I not be able to use the bathroom?"
Not long. The bathtub door is usually installed in one day, a non-slip coating takes about two hours. For a shower instead of the tub, allow 2 to 3 days.
"I can't possibly afford that."
There are often grants available. With a recognised care level, the care fund in Germany pays up to €4,180, and in Austria, the federal states provide funding. You will know the price before the order: a fixed price after the inspection.

„Once the bureaucracy was taken care of, everything went really quickly. From planning the accessible bathroom remodel to the execution, everything was truly perfect. Every wish was taken into account, every question answered. The workers who renovated the bathroom were prepared for everything. I had water damage that wasn’t visible beforehand. They had a solution ready in no time. One more thing I have to say: the way these craftsmen worked so cleanly was amazing. They immediately swept everything up and disposed of it. I didn’t have any trash left behind. A big THANK YOU to everyone, I can only recommend the company. Anytime again!!"

„I had Bazuba remove the bathtub and shower and install a barrier-free shower. The project was done very well from start to finish. Friendly staff, on-time and clean work, good quality, and always checking and asking if everything was okay complete the positive overall impression. I'm very happy with the new shower. I would always recommend the company."

„Nine years ago, we had our bathtub reglazed (we could use it again after 24 hours), and now – age-appropriate – the bathtub was taken out and a shower put in (we can shower again after 72 hours). In both cases, great expert advice, a quick appointment for the remodel, very friendly and professional staff, very clean work. Simply a great service. Thanks."

„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."

FREQUENT QUESTIONS
Questions about accessible bathrooms
What is the difference between accessible and partially accessible?
A bathroom is considered wheelchair accessible if it meets the requirements of DIN 18040-2, such as a level-access shower, sufficient manoeuvring space, and wide doors. ‚Accessible‘ means that the main obstacles have been removed, without necessarily complying with every aspect of the standard. In existing homes, accessible solutions are often the realistic option, for example with a bathtub door or a shower with a low entry. You can read more about this in the guide. Wheelchair accessible or suitable for seniors.
Senior bathroom, age-appropriate or wheelchair accessible bathroom: What is the difference?
Senior bathroom, senior-friendly and age-appropriate bathroom are not standardised terms. They refer to a bathroom that remains comfortable and safe as you get older: low entry to the bath or shower, slip-resistant surfaces, grab rails, a seating option, and enough space to move around. In everyday language, wheelchair accessible is often used synonymously with barrier-free. There is a standard for this: DIN 18040-2. It distinguishes between bathrooms that are accessible and those that are fully usable with a wheelchair, which require larger movement areas. In existing buildings, it is often not possible to fully comply with the standard. In such cases, the term ‚low-barrier‘ is used, and this is exactly where bathtub door, bath to shower conversion, and slip resistance come into play.
How long does an accessible bathroom renovation take?
That depends on the solution. A bathtub door is usually installed in one day, a non-slip coating takes around two hours. For “Tub out, shower in”, allow 2 to 3 days. A larger renovation with a new room layout takes longer. You will receive the exact schedule after the inspection.
How much does a barrier-free bathroom cost?
The costs depend on what is being renovated. Installing a door in the existing bathtub is a smaller intervention than a new shower or a complete remodel. The size of the bathroom and the fittings also play a role. After a free on-site inspection, you will receive a fixed price from us. Grants from the care insurance fund in Germany or from the federal states in Austria can significantly reduce your own contribution.
You can find more figures, examples by bathroom size, and our price calculator in the guide. Bathroom renovation costs.
What funding is available for a barrier-free bathroom?
In Germany, the long-term care insurance fund pays up to €4,180 for measures that improve the living environment for those with a recognised care level, which also includes bathroom renovation. The KfW grant 455-B can no longer be applied for as of 31 July 2026, but the KfW loan 159 ‚Age-appropriate Conversion‘ remains available. In Austria, the federal states provide funding, for example in Vienna up to €7,500. Please submit your application before work begins. You can find all details in the guide. KfW funding and long-term care insurance.
What measurements does a barrier-free bathroom require?
For KfW funding, requirements include a manoeuvring space of at least 0.90 × 1.20 m in front of each sanitary fixture, a door width of at least 0.80 m, and a level-access shower with a maximum drop of 20 mm. DIN 18040-2 is stricter and requires manoeuvring spaces of 1.50 × 1.50 m for wheelchair-accessible bathrooms. The most important values can be found in the table above.
Can I still bathe despite bathtub door?
Yes. The door is fitted into your existing bathtub and sealed. When closed, it keeps the water in the tub, so you can still enjoy a full bath. To get in, simply open the door—no need to climb over the high edge of the tub.
Can I renovate my bathroom to be accessible as a tenant?
Yes, but please speak to your landlord beforehand. In Germany, tenants can request that the landlord allows structural changes that serve the needs of people with disabilities, according to § 554 BGB. The landlord may only refuse if the renovation is unreasonable for them, even after considering your interests. In Austria, it depends on the tenancy agreement and the Tenancy Act. A bathtub door or a non-slip coating are relatively minor interventions.
