Bathroom Renovation Quotation Checklist for Malaysia
Compare bathroom quotations by demolition, substrate repair, waterproofing, falls, drains, tiles, sanitary fittings, testing and making good.
Direct answer：Bathroom quotations often look similar while allocating very different hidden work. Compare the demolition boundary, substrate repair, waterproofing details, drainage falls, penetrations, tiling system, fitting installation and test evidence line by line.
How to use this guide: replace every point below with the property's actual dimensions, named responsibilities, approved drawings and written evidence before using it for quotation, approval or construction decisions.
Record the existing condition
Photograph leakage signs, cracks, hollow tiles, drainage, ceiling below, access panels, services and neighbouring finishes. State what remains subject to opening-up inspection.
Define demolition and substrate repair
List tiles, screed, fixtures, screens, ceilings, pipes, disposal, protection and repair. Avoid assuming the exposed base will need no correction.
Specify the waterproofing system
Identify area, substrate, compatible details, coats or membrane, penetrations, curing, protection and pre-cover inspection according to current product guidance.
Coordinate falls, drains and tile layout
Confirm drain locations, shower boundary, finished levels, thresholds, niches, tile sizes, cuts, trims, grout and access before setting out.
Allocate fittings, testing and making good
State who supplies and installs each fitting, connects and tests services, seals interfaces, repairs adjacent areas, cleans and records defects.

Only to the extent inspection allows; unresolved conditions should be identified and controlled.
Who repairs damage outside the bathroom?
Allocate investigation and making-good responsibility in the quotation and contract.
