—Renovation and tiling

What drives the cost of a pool renovation

Renovation costs vary from a regrout to a full rebuild of the interior. The scope, and what is found once work starts, decide where yours falls.

The biggest factor is extent: regrouting is very different from stripping the finish, renewing waterproofing and retiling. Materials matter too — plaster, ceramic, porcelain and glass mosaic differ in cost and in labour. Coping and deck replacement add further work.

Renovation guides cover work on a pool that already exists: its surface, its waterproofing and sometimes its structure.

Hidden defects found after stripping — damaged render, cracks, failed waterproofing — can add work, which is why a renovation quotation should explain how such findings are handled. Equipment upgrades, lighting changes and access difficulties also affect the total. An itemised quotation shows where the money goes.

01Summary

What matters most here

  • Extent is the main driver

    Grout, finish or structure.

  • Materials vary widely

    Plaster to glass mosaic.

  • Hidden defects

    Found once finishes come off.

02Detail

Cost factors

  • Scope

    Whether the job is a regrout, a refinish, new waterproofing or structural repair is the biggest single driver of the price.

  • Finish material

    Plaster, tile or mosaic.

  • Coping and deck

    Re-lay or replace.

  • Repairs

    Substrate, cracks and fittings.

  • Equipment

    Pumps, filters, lights and controls.

03Before you start

When comparing quotes

  • Compare scopes

    Not just totals.

  • Ask about provisional items

    For hidden defects.

  • Check exclusions

    Deck, equipment and electrics.

—In practice

How to use this

Define the extent clearly — regrout, waterline band, full retile, waterproofing, coping, equipment — and ask for each part to be priced as its own line, which shows where the budget is actually going. Ask how hidden defects will be assessed and priced if they appear, and compare quotes only on the same scope and materials.

Mistakes worth avoiding

Comparing different scopes
A cheaper quote may simply leave out waterproofing, coping or making good. Align the scope before comparing prices.
Allowing no contingency
Hidden defects are common once older finishes come off. A sensible allowance avoids difficult decisions mid-project.

04FAQ

Common questions about this

Why might the price change during work?
Hidden defects can appear once finishes are removed; agree how they are handled.
Is retiling more than replastering?
Usually, depending on tile type and preparation.
Should equipment be included?
If it is ageing, upgrading at the same time avoids a second disruption.
How do I compare quotes?
Line up scopes and materials side by side.
Does access affect renovation cost?
Yes. Difficult access for materials and removal of old finishes adds labour.
