Planning example — not a documented completed case. This resource addresses upper-floor shower drainage and waterproofing. No specific client, completed work, project price, duration or approval is established here. Use it to prepare a scope conversation and compare it with the conditions of your own property.
Images on this page are visual references. They are not verified photographs documenting Corniel’s execution of the scenario below.
Establish where water can travel
Begin a proposed upper-floor shower with the existing supply, waste and vent conditions. Record accessible connection points and the route to the proposed shower position. A layout sketch alone does not establish that a drain can be routed as drawn. Have the responsible professionals review the proposed arrangement, access needs and the applicable requirements. Identify finished rooms below that could be affected by investigation or construction and include their protection and restoration in the scope.
Choose a coordinated shower assembly
Discuss the receptor, drain, membrane, wall substrate, transitions and penetrations as one assembly. Select products through their current installation instructions and the project design, rather than mixing components because their finishes look compatible. Ask how the installation will be checked and what evidence is expected before tile conceals it. This is a planning requirement, not a claim that a shower is leak-proof or that a particular test has already passed.
Review fixtures and service needs
A multi-outlet shower requires coordination beyond choosing attractive trim. Confirm the selected valves and outlets, their installation requirements, available utility conditions and the maintenance access that the design must retain. Position controls with entry and daily use in mind. Review the location of glass, door movement and ventilation with the rest of the room. Do not infer a building-wide restriction from another property; ask management for the written rules that actually apply.
Keep verification separate from visual completion
A polished tile surface does not document concealed work. The project record should distinguish installation photographs, product instructions, checks performed, applicable inspection records and remaining corrections. Define who accepts each stage and how that acceptance is recorded. The proposed final appearance belongs in the design brief; a completed result requires its own evidence. This example discusses an upper-floor shower scope without asserting that Corniel built the shower described in an earlier legacy narrative.

Obtain quotations against a written scope and selected products. Ask each proposal to identify labor, materials, access and protection arrangements, work by others, inclusions and exclusions. Keep allowances and unresolved existing conditions visible so they can be reviewed when more information is available. Compare proposed substitutions on scope and installation requirements, not only total price. A working budget should identify the decisions needed to release it and how a scope change will be approved. This example establishes no standard Manhattan price, per-square-foot rate, insurance limit or claimed saving.
Build the working schedule from verified dependencies
Base the working sequence on design releases, the actual review requirements, supplier information, access arrangements and trade coordination. Record which assumptions have been confirmed and which remain open. Where inspections or utility coordination apply, identify the responsible party and the relationship to later work. Agree on how a discovery or late selection changes the sequence. Do not treat a generic number of weeks or months as a verified schedule. The project team should maintain a current plan tied to the accepted scope and available information.
Keep a record that can support a genuine case later
Retain the accepted scope, relevant drawings, recorded changes, applicable review records and photographs of the work actually performed. A finished image cannot establish concealed installation, project cost, client satisfaction or agency acceptance by itself. Separate design references from project evidence and record the context of any photographed work. If a complete project record becomes available, it can support a separately verified case. Until then, this page remains a prospective planning example and provides no documentary claim of a completed Corniel Construction job.

Prepare for the scope review
Bring measured information, relevant property documents and your priorities for upper-floor shower drainage and waterproofing. Note which choices are essential and which can change. Use the review to assign unresolved questions to the appropriate professional and agree on the information needed before accepting the proposed scope.
