Bathroom Renovation Quotes Singapore: Scope, Waterproofing and Fittings

A bathroom renovation quotation should explain the work beneath the finishes as clearly as the fittings you can see. Before comparing proposals, confirm whether each firm is pricing a fixture refresh, an overlay approach or removal and replacement of existing finishes. These are different scopes and should not be compared by total price alone.

Use this guide to prepare questions for your contractor and relevant qualified trades. The correct method depends on the condition of your bathroom and the requirements applying to your property.

Define exactly what is being replaced

List the toilet, basin, taps, shower fittings, vanity, mirror, accessories and shower screen. State which you will supply and which the firm should include. Include removal of old items, installation, connections and making good where needed.

For tiles and surfaces, ask whether the quotation covers walls, floors or selected areas. Check quantities, material allowances, tile sizes and any special installation charges. A visual reference helps communicate style, but the final specification needs actual product details.

Check HDB restrictions before choosing the method

HDB states that newly built flats have a three-year restriction on removing bathroom and toilet wall and floor finishes. Check the applicable guidance for your flat before agreeing to removal or other affected work.

Ask the firm to explain whether the proposed method is permitted and what approvals or professional assessment are needed. Do not assume that covering an existing finish or changing a fitting is suitable simply because it involves less visible demolition. Confirm the requirements for the exact proposed work.

Ask what the waterproofing scope includes

If the proposal involves waterproofing work, ask for the system, areas covered, substrate preparation, junction treatment and sequence to be described. Clarify who carries it out, what checks are included and what documentation you receive at handover.

Ask how the firm will address any existing signs of leakage and whether further assessment is needed before the scope can be finalised. A new tile surface alone does not explain what happens to the underlying waterproofing. Avoid agreeing to a method solely from a generic package description.

Record the warranty scope and exclusions, who responds to a reported problem and how a concern affecting neighbouring property would be investigated. Do not interpret a warranty as a promise that every possible cause of leakage is covered.

Separate plumbing, fittings and electrical work

Confirm replacement and relocation of pipes, connection of taps and sanitary fittings, and any associated making good. Ask who supplies the fittings and what happens if an owner-supplied product is incompatible or arrives late.

For water heaters, lighting and other electrical items, confirm the relevant qualified worker and installation scope. Discuss safe placement and connections with that professional. Product selection and technical installation requirements need to be coordinated before finishes are completed.

Check drainage, shower screens and cleaning access

Ask the firm to explain how the proposed floor and shower arrangement supports drainage and how it will be checked. Discuss level transitions, the entrance, screen opening and access for cleaning. Choose a layout that works for the people using the bathroom rather than copying a large showroom arrangement into a compact room.

For screens and vanities, specify dimensions, materials, hardware and installation. Confirm sealant work, accessories, disposal and final cleaning. Where measurements are provisional, ask when the final amount will be approved.

Compare the full quotation before appointing a firm

Ask each firm to identify removal, protection, debris disposal, tiling, waterproofing, plumbing, electrical work, fittings, installation and exclusions. Match the tax basis and total payable. Have provisional items and the variation approval process recorded in writing.

Use the wider comparison guide at the “Compare Renovation Quotations in Singapore” guide linked in Sources & references to organise the proposals. Confirm the expected disruption, access requirements and arrangements if this is the home’s only available bathroom.

Frequently asked questions

Can I renovate a bathroom without replacing every fitting?

Ask for a clearly defined refresh scope and an assessment of compatibility with retained items. Confirm the making-good and installation work that remains necessary.

Is waterproofing included in every bathroom package?

Do not assume it is. Ask the firm to describe exactly what is included and why that method suits your bathroom.

Should I choose an overlay or remove the existing finishes?

Have the firm assess the existing condition, constraints and applicable rules. Request the reasons, limitations and complete scope for its recommendation.
