Bathtub to shower conversions in Marbella
Replacing a bathtub with a shower can make a bathroom easier to use. A well-defined conversion starts with drainage, available floor depth, surrounding finishes and the elements you want to keep.

What the assessment covers
We start with the bath dimensions and the way it is installed. We review the space for the new shower, the position of the waste outlet and the depth needed for drainage. The shower solution, taps, screen and finishes can then be specified together.
- Removing the bath and the affected materials.
- Adapting water supply and drainage for the selected fittings.
- Preparing the substrate and waterproofing the intervention area.
- Installing the shower and reinstating the agreed wall finishes.
- Fitting the taps, screen and finishing details included in the quote.
Keeping existing tiles or changing the finish
A bathtub can conceal unfinished areas or leave damaged surfaces when removed. Without spare tiles, the exposed strip needs a considered solution: a compatible material, a deliberate contrast or a wider renewal of that wall.
Photographs help us discuss options, but the condition of the substrate needs appropriate inspection. If you want to change the whole space, see our bathroom renovation service in Marbella.
Access, floor height and everyday use
A level-access shower depends on the existing construction and drainage. Choosing a slim tray is not always enough. Available depth and the junction with the bathroom floor need review before a finished arrangement can be confirmed.
Tell us if the aim is easier access, space for assistance or provision for a seat or grab rails. These needs should be considered from the start, together with clear opening width and the way the screen operates.
What affects the cost and timing
The dimensions, installation changes, substrate condition and selected products all affect the quote. Availability of the screen and taps, along with material application times, also affects scheduling.
We define the scope by item so labour, installation materials and fittings can be distinguished. Use our quotation checklist, then send photographs, approximate dimensions and the property location to begin the review.
Frequently asked questions
Can the bath be replaced without renovating the whole bathroom?
Often the work can be limited to the bath area. This depends on the existing installations, substrate and how affected finishes can be reinstated.
Can you install a level-access shower?
This is assessed after checking the available depth and drainage. If it is not feasible, a solution compatible with the existing construction is considered.
Should I buy the tray and screen first?
It is better to confirm measurements and compatibility first. If you have selected products, send their references and specifications so installation can be reviewed.
