Plan a bathroom remodel around waterproofing and layout

Begin with the daily use of the room

Draw how people enter, reach storage, use fixtures and move between wet and dry areas. List what is missing today, such as towel storage, a better shower entry or space to help another person. Keep essential functions separate from decorative preferences.

Confirm the products whose dimensions affect the plan early: tub, shower base, vanity, toilet, enclosure and major accessories. A picture of a fixture does not establish how its controls, access panels and service connections fit the room.

Ask for a named wet-area system

Schluter’s technical guidance explains that a tile surface is not, by itself, the complete waterproofing system. Ask the designer or installer to identify the selected assembly and its instructions, including the substrate, drain connection and transitions.

Have the team coordinate niches, benches, enclosure fixings and accessories before the wet-area work is built. Ask how penetrations and adjoining surfaces are treated within the chosen system. These are review questions for qualified installers, not instructions for improvising a hybrid assembly.

Resolve the hidden and visible details together

Ask about the existing floor and wall condition, any suspected moisture damage and what investigation is included. The proposal should explain how discoveries are documented and approved. Covering an unknown condition with attractive tile does not answer the underlying question.

Coordinate bathroom exhaust, electrical work, lighting and service access with the room layout. Review the shower entry and finished-floor transition before choosing tile thicknesses or an enclosure.

• Who supplies the complete waterproofing and drainage specification?
• What checks or tests occur before the work is covered?
• Who documents concealed conditions and accepted changes?
• How are plumbing and enclosure details coordinated?
• What cleaning and maintenance instructions come with the selected products?

Make handover part of the scope

Request the product names, care instructions, relevant inspection records and written warranties. Ask whom to contact if an issue appears and how the condition should be documented without disturbing the work.

Agree on a punch-list review for fixture operation, storage, lighting, visible finishes and the items that can be observed safely. A homeowner walkthrough complements professional quality control; it cannot verify everything behind a finished wall. Keep that distinction clear when approving completion.
