Walk-in shower or bathtub: choose for your needs and your home
Published on 31 July 2026 · Verified on 18 September 2026 · The Mestravaux.lu team
The choice depends on washing habits, users and what the building allows. A level-access shower may require floor alterations; a bath that is actually used can remain worthwhile. Compare both options on a dimensioned plan and quotations covering the same scope.
The essentials in 30 seconds
- Describe current use and any assistance needs.
- Check space with doors and drawers open.
- Have drainage assessed before promising level access.
- Compare the complete renovation rather than equipment prices alone.

Start with use, without assuming a winner
Bathing, standing or seated showering and assisted washing require different arrangements. Separate essential uses from preferences. A bath for children or relaxation and a shower designed for easier transfers meet different needs. Do not decide solely on an assumed resale premium.

Plan the room as it will be used
Show the door, furniture, screen, taps and access to other fixtures. Simulate opening and movement. Equipment footprint alone does not establish usable space. Include access to the trap and serviceable components.
Check the floor, drainage and waterproofing
Ask what height is available for the shower base, trap and drain connection. Specify the waterproofing system and junctions; Buildwise addresses membrane and surface finish separately. Choose tiled shower or tray after this assessment, with appropriate consent if a floor structure or shared area is affected.
Assess accessibility as a whole
For disability or dependency adaptations, define transfer, support and assistance requirements before purchasing. Long-term care insurance requires assessment and AEC approval before work, without retrospective funding. A separate special-adaptation grant exists subject to conditions. Check the individual case with the responsible body.

Request a quoteCompare water without a universal ratio
Shower volume depends on actual flow multiplied by running time. Bath volume depends on actual filling. Compare habits and equipment characteristics; a product name establishes neither annual savings nor a fixed bath-to-shower ratio. Hot-water production also affects cost.
Compare work and maintenance
Request both options including removal, pipes, substrate preparation, waterproofing, equipment, screen and finishes. Identify changes if the drain stays in place. Check cleaning access, joints, trap removal and spare parts. No local average price is established here without comparable quotations.
Frequently asked questions
Is a walk-in shower always level access?
Available height and drainage determine the result. Confirm finished levels on the plan before ordering.
Does a low tray alone make a shower accessible?
No. Access, movement, transfers, supports and assistance must be assessed together.
Does showering always use less water?
It depends on flow, duration and the bath fill used for comparison.
Should work start before applying for support?
For long-term care insurance, wait for assessment and AEC approval. Check other schemes separately.
Which is cheaper?
Compare complete options for your property, especially floor and drain alterations.
