Pick the bathing format by use
Decide whether the room needs a tub, walk-in shower, tub-and-shower combination or a more accessible entry. Consider who bathes, whether children use the tub, how balance may change, cleaning preferences and the available floor area. A conversion that improves access can still create splash, door or storage problems if the whole room is ignored.
Name every layer under the finish
Tiled showers can use different accepted water-management approaches. The important step is not choosing a brand from an article; it is asking for one coherent assembly. The proposal should identify the base or sloped bed, drain type, backing surface (often called the substrate), membrane or liner, corner treatment, penetrations, wall-to-floor connection and how the curb or entry is built.
Tiled-shower water-management guidance explains why this matters: ceramic and stone coverings are not themselves waterproof. Water has to be directed to the drain by the assembly behind the visible finish. Avoid mixing isolated components without confirming compatibility and installation requirements.
Follow water through the drain and transitions
Ask where surface water goes, how the floor slopes and how waterproofing connects to the drain. Record the treatment around the valve, shower arm, niche, bench, grab-bar fasteners and glass anchors. At the bathroom floor, specify the height change and where the shower waterproofing stops.
If the design is barrier-free, the sloped area, splash control and floor outside the shower need to work together. A broad opening may require more waterproofed floor area and careful planning around the vanity and toilet.
Confirm support before closing the walls
Glass, seats, shelves and future support bars need suitable backing or approved anchoring. Put locations in the drawing while framing is visible. A note reading “add blocking” is incomplete unless it includes the wall, height range and intended fixture.
In an older El Paso building, verify the wall material and any earlier alterations before choosing fasteners or support details. A newer framed home and an adobe or brick building may need different site-specific answers.
Make testing a named responsibility
The scope should say who inspects seams and penetrations, whether the selected system requires a water test, when that test happens and what record is retained. Testing after tile covers the assembly cannot show the same details as an inspection before finishes.
Account for glass, niches and benches
Glass dimensions are affected by finished tile thickness and wall alignment. Record where the support is located and whether hardware penetrates waterproofed surfaces. Niches and benches create extra corners and changes in plane; they need the same water-management detail as the main wall.
Add a maintenance plan
Ask which joints use flexible sealant, which cleaners are compatible and how drains or tracks can be serviced. Record manufacturer documents and installed-product names. A durable assembly still needs maintenance, and a homeowner should be able to identify the system after the installer leaves.
Coordinate moisture removal outside the shower
El Paso’s dry outdoor climate does not make bathroom exhaust optional. Steam remains concentrated indoors. EPA remodeling guidance says exhaust should discharge outdoors rather than into an attic or cavity. Record fan capacity, duct route, termination, controls and who verifies operation.
Use the connected-systems guide for the fan and electrical work, and the full-remodel comparison if you are deciding between a tub- or shower-only package and a whole-room renovation.
Frequently asked questions
Is tile waterproof by itself?
No. The visible tile and grout need a suitable water-management assembly behind them.
Should waterproofing be tested before tile?
For the KERDI system, Schluter’s KERDI-Shower-Kit installation instructions recommend a water test before tile to check for leaks and note that officials may require one. Confirm the selected manufacturer, test timing, responsible person and local inspection requirement for your project.
Does a tub-to-shower conversion include the rest of the bathroom?
Not necessarily. The written proposal must say whether flooring, vanity, lighting, ventilation, painting and connected repairs are included.
