Estimate a bathroom renovation budget in seconds — pick the finish level, enter how many bathrooms, then add the extras that move the price most. Indicative 2026 Klang Valley ranges from our bathroom renovation cost guide, shown as a range, never a fake exact figure.
The toilet drain is cast into the slab. Keep it where it is if you can — moving it means core-drilling.
The premium level already assumes large-format tiles, so this option applies to basic and mid-range only.
The mid-range level already includes a water heater.
Bathroom renovation in the Klang Valley is budgeted per bathroom, so the calculator starts from the range for the level you pick and multiplies it by the number of bathrooms. A basic refresh — re-tiling with a new toilet, basin, tap and shower set — is RM6,000–RM10,000 per bathroom. A mid-range remodel with a full re-tile, proper waterproofing, a vanity, a glass screen and a water heater is RM12,000–RM18,000. A premium bathroom with large-format tiles, a rain shower, a custom vanity and a feature wall is RM20,000–RM35,000+, and the plus sign stays because the top end is open.
Three extras are added only when they apply, because they are the lines that surprise people most. Moving the toilet or the floor trap means core-drilling through the slab and adds RM2,000–RM5,000 for each bathroom where it happens. Switching from standard tiles to large-format or imported tiles adds RM2,000–RM5,000. On the basic level, an instant water heater adds RM300–RM600 installed; the mid-range level already includes one.
Every figure comes from our bathroom renovation cost guide. The one line we would never cut is waterproofing: a cheap membrane is the most common reason a bathroom leaks into the unit below. When you have a range you are comfortable with, WhatsApp ClickBina photos of the bathroom and rough measurements. When the bathroom is part of a whole-house refurbishment, we coordinate the trades — tiling, plumbing, waterproofing and fittings — under one flat price with no hidden charges; for a bathroom-only job, WhatsApp us your job details for a quote. A site visit is RM150, waived if you go ahead with us.
Estimate = level range × number of bathrooms + RM2,000–RM5,000 × bathrooms where the toilet or floor trap moves + RM2,000–RM5,000 × bathrooms (tile upgrade, basic or mid-range) + RM300–RM600 × bathrooms (instant heater, basic level only). Low ends and high ends are added separately, so the answer stays a range.
| Factor | How it changes your quote |
|---|---|
| Level of finish | Basic keeps the layout and swaps the fittings; mid-range adds waterproofing, a vanity and a glass screen; premium changes the whole look. |
| Hacking or overlay | Hacking the old tiles down to the substrate costs more than tiling over, but it is the only way to renew the waterproofing properly. |
| Moving points | Keeping the toilet, floor trap and shower where they are is the biggest single saving in a bathroom renovation. |
| Tile size and brand | Large-format and imported tiles cost more to buy and to lay, and need a flatter wall. |
| Sanitaryware | A budget toilet and basin suit a rental; a mid-range brand makes sense in a bathroom you will use for a long time. |
| Waterproofing | A full membrane with a proper wall turn-up protects the unit below. Skimping here is the most expensive saving you can make. |
