Bathroom Renovation Cost Calculator — Every Stage Priced
Demolition, plumbing rough-in, waterproofing, tiling, sanitaryware by brand class, shower glass — the six stages of a proper bathroom redo, each priced as its own line, in the order a good contractor actually executes them.
Essential
₹88,000 – ₹2,00,000
Standard
₹1.3 – 3 lakh
Premium
₹2.3 – 5.1 lakh
For a typical configuration — adjust every parameter below. Indicative, confirmed after site assessment.
- Written scope & quotation before any commitment
- One accountable coordinator, start to finish
- Screened execution professionals
- Stage-by-stage payments, reviewed before the next stage
- We never sell your requirement to contractors
A bathroom renovation done right is a strict sequence: strip everything, redo the supply and drainage lines while the walls are open, waterproof the shell, tile, then fit sanitaryware and glass. The stage that decides whether the renovation lasts is the one you cannot see afterwards — waterproofing — and it costs ₹8,000–20,000 against the lakhs of damage its absence causes to the flat below.
This calculator prices each stage separately, with the sanitaryware brand ladder (Cera/Hindware → Jaquar → Kohler) as the tier decision it really is. Compare any contractor quote stage by stage: the missing waterproofing line and the vague "fittings as per selection" clause are the two classic tells.

- Rain shower, niche detailing, premium glass
Where can I save?
Keep the sanitary positions
₹15–30k/bathroomMoving the EWC or drain line means breaking the slab and re-sloping drainage — ₹15–30k per moved position. Renovating in place keeps the rough-in line minimal.
Jaquar body, Kohler feel
20–35% of fixturesA Jaquar concealed cistern with a premium flush plate and a good rain shower reads as a luxury bathroom at half the Kohler-everything fixtures bill.
Tile the feature wall only
₹8–20k/bathroomPremium tiles on the one wall you see from the door, standard GVT elsewhere — the designer look at a fraction of the premium-tile spend.

What moves this cost most
- Sanitaryware brand class — Cera to Kohler is a 5× swing on the fixtures line
- Plumbing scope — skipping the rough-in redo saves ₹15–40k now and risks all of it later
- Tile selection — the feature-wall habit adds fast at premium tile rates
- Bathroom count — stages parallelise, but materials scale linearly
Commonly excluded from quotes
- Geyser/water heater and its electrical point
- Exhaust fan and ventilation ducting changes
- Door replacement (add ₹9–16k if the frame is water-damaged)
- Structural slab repairs if demolition reveals damage
Hidden costs to budget for
- Society permissions and debris-lowering charges in apartments
- Downstairs neighbour coordination if old leaks left damage
- Concealed-cistern frames and flush plates priced as "extras"
- "Fittings as per selection" clauses — pin the brand and model list before signing
Common questions
What does a bathroom renovation cost in Bengaluru in 2026?
A full strip-and-redo computes ₹1.3–3 lakh at Standard tier (Jaquar class) per bathroom on this model, including demolition, plumbing redo, waterproofing, tiling and GST. Essential runs ₹0.9–2 lakh; Premium ₹2.3–5.1 lakh. Quotes below a lakh usually skip the plumbing redo or the waterproofing membrane — ask.
Can I renovate a bathroom without breaking tiles?
Cosmetic refreshes (fixtures, glass, regrouting) work when the waterproofing and plumbing are sound. On 15+ year bathrooms the honest answer is usually no — old lines behind new tiles are a deferred invoice.
How long does one bathroom take?
Ten to fifteen working days done properly — demolition and rough-in are quick; waterproofing needs curing time you should refuse to compress. Two bathrooms in parallel take barely longer than one.
