What are you buying when a quote says “new tiled shower”?
You are buying a connected assembly. Water must move toward the drain at the surface, while the concealed system protects the structure when moisture passes through joints or reaches vulnerable transitions. The details at corners, niches, benches, curbs, doors and plumbing penetrations matter as much as the open wall.
A complete shower scope should identify:
- demolition and assessment of the existing wet area;
- drain type and connection responsibility;
- base or pan and how slope is formed;
- wall substrate and preparation standard;
- waterproofing product or system and its compatible accessories;
- treatment of seams, fasteners and valve penetrations;
- curb, doorway or curbless transition details;
- tile area, layout, cuts, edge treatment and movement joints;
- grout and sealant locations;
- glass attachment and any required blocking;
- evidence retained before the work is covered.
The objective is not to force one brand. It is to prevent a quote from naming the decorative layer while leaving the concealed assembly undefined.
How should different waterproofing approaches be compared?
Ask each provider to describe the complete method they will install and the product instructions they will follow. Common approaches can use sheet membranes, liquid-applied membranes, systems adhered to the substrate or other approved assemblies. Products are not automatically interchangeable. Mixing components from different systems may change installation requirements or manufacturer support.
Compare preparation, overlaps, thickness or coverage where relevant, cure times, compatible drain details and the treatment of transitions. Ask who checks the work and what photos or records will be provided before tile begins. A brand name without installation details does not establish quality.
Which shower features need early decisions?
Niches, benches, grab bars, handheld showers and glass all require coordination. A niche must fit the framing and tile layout while maintaining waterproof continuity. Grab bars need suitable support at exact locations. A handheld outlet and diverter change the plumbing rough-in. Frameless glass may need backing and should not be treated as an afterthought that creates avoidable penetrations.
A curbless design requires special attention to elevation, slope, doorway containment and the floor outside the shower. Confirm feasibility before ordering a drain or starting demolition. If a curbless transition cannot be achieved within the existing framing and room conditions, the plan should show the alternative rather than conceal the issue.
How does tile choice change the work?
Tile affects more than appearance. Size and flatness can influence wall preparation. Pattern and alignment affect waste and labor. Natural stone may bring different handling and maintenance needs. Small shower-floor tile must follow the base while maintaining drainage. Edge trims, finished tile edges or stone pieces should be selected before layout begins.
Ask for a layout review before setting. It should address focal walls, grout-joint alignment, cuts at corners and fixtures, niche placement, transitions and the height at which different finishes meet. Record who supplies extra tile for waste and future repair.
What evidence should exist before tile hides the system?
The contract can require simple, useful documentation:
- Photos of exposed framing and subfloor after demolition.
- Photos of any repairs and the drain connection before concealment.
- Photos of the completed substrate and waterproofing, including corners and penetrations.
- The product names and relevant installation records.
- Any required inspection or test result.
Do not assume every system uses the same test or timing. Ask what the selected manufacturer requires and what the local authority expects for the permitted project. The permit guide helps identify that authority.
How should water damage be priced?
Visible staining does not reveal the full repair. The base proposal should state what can be seen, what is assumed and what repair work is included. Once demolition exposes the structure, the provider can document the condition and price any work outside the base scope under the agreed change process.
Avoid two weak extremes: pretending there is no risk, or adding an unexplained contingency that cannot be reconciled. A written allowance or unit rate tied to documented conditions is easier to evaluate.
How do Greenville, SC permits enter a shower remodel?
Replacing finishes only may be treated differently from altering plumbing, electrical systems or the building structure. The responsible office decides the requirement. Inside City of Greenville jurisdiction, review the city’s Do You Need a Permit guidance. For unincorporated county properties, use Greenville County Building Safety. Other included municipalities have separate guidance linked from the local permit page.
Do not let a tile installer’s narrow scope obscure plumbing or electrical work performed by others. The written plan should name every trade and who coordinates inspections.
What belongs in the quote comparison?
Create separate rows for demolition, repairs, drain, base, substrate, waterproofing, tile, edge finish, grout, sealant, glass, fixtures and documentation. Add the exact tile allowance and the assumed tile size or pattern. Use the quote comparison checklist for the rest of the room, including vanity, flooring, paint, electrical and ventilation. Check the 2026 cost guide before you compare tile and glass allowances.
What should you see before tile starts?
Look at the bare base. Check its slope. Find the drain link. View each wall face. Check all inside corners. Check the door edge. Find the niche seams. Find each pipe seal. Ask which parts form one system. Read the product sheet. Take clear photos. Note the review date. Do not cover a loose edge. Do not hide an open hole. Fix the issue first. Then record the finished membrane. This takes little time and keeps the hidden work clear.
Tile can wait one more day. Hidden water work cannot be fixed with new grout. Ask the installer to show the plan. Ask what is still open. Write down the answer. Let the next step start only when the base work is ready.
Frequently asked questions
Is grout waterproof?
Do not rely on grout as the concealed water-control plan. The proposal should describe the complete shower assembly behind and below the tile.
Should the shower be tested before tile?
Ask what testing or inspection applies to the selected assembly and jurisdiction, and when it occurs. The provider should follow product instructions and local requirements rather than promise one universal test for every system.
Can existing shower walls be tiled over?
Sometimes a specific approved system may allow work over suitable materials, but the condition, flatness, bond and water-control strategy must be established. A visual finish alone cannot confirm the hidden assembly is sound.
