The traditional approach, item by item
Stone instead of tile
Kota in a honed finish for the floor at ₹90–₹180 per sq ft, Jaisalmer or Tandur on the walls, or a honed granite for a darker room. Laid in larger pieces with tight joints, it gives a bathroom a solidity that 600 × 600 ceramic does not.
Brass and gunmetal fittings
Cast brass or gunmetal taps and shower fittings, unlacquered so they patinate, or PVD-coated if you want the colour held. Expect ₹45,000–₹1.2 lakh for a full set. They are repairable, which modern cartridge mixers often are not.
A teak-framed mirror and vanity
Solid teak framing around the mirror and on the vanity, marine-grade or properly sealed, with a stone top. Teak is the one timber that belongs in a bathroom and it has been used in Indian coastal buildings for centuries.
A jali ventilator
A carved stone or teak jali panel in the external wall above door height, in place of or alongside the exhaust. Continuous passive air movement is why old Indian bathrooms did not smell, and it still works.
The traditional Indian bathroom palette
Earth tones and metal. The stone sets the palette and everything else follows it, which is the reverse of a modern bathroom where the tile is chosen last.

Specification for a stone bathroom
- Kota honed rather than polished, laid with a 2 mm joint and sealed. Polished Kota is slippery when wet; honed has a natural grip and is the correct finish for a bathroom floor.
- Cast brass or gunmetal fittings with replaceable washers or cartridges. Unlacquered brass patinates to a warm brown and can be polished back; PVD holds the new colour permanently. Both outlast plated zinc by decades.
- Marine-grade or properly sealed teak for the frame and vanity, with an end-grain seal on every cut. Teak is naturally oily and suits a bathroom; any other timber does not.
- A jali ventilator only in an external wall, with an insect mesh behind. In an internal bathroom it has nowhere to draw from and a ducted exhaust remains necessary.
What a traditional stone bathroom costs
| Element | Specification | 2026 Mumbai cost |
|---|---|---|
| Stone | Kota floor and Jaisalmer or Tandur wall dado, honed, cut, laid and sealed | ₹1,05,000 |
| Brassware and sanitaryware | Cast brass or gunmetal set, WC, basin, health faucet | ₹95,000 |
| Teak vanity and mirror | Solid teak framed vanity with a stone top and a framed mirror | ₹68,000 |
| Civil and waterproofing | Strip-out, membrane, ponding test, falls, bedding for stone | ₹58,000 |
| Jali ventilator and screen | Carved stone or teak jali in the external wall with mesh | ₹34,000 |
| Lighting | Warm wall lights either side of the mirror, one ceiling fitting | ₹26,000 |
Total at this specification: ₹3,86,000 ex-GST. Add 18% GST. Stone is heavier than tile: a Kota and Jaisalmer bathroom adds roughly 25–40 kg per square metre over a ceramic one, which is worth confirming in an older building.
Three mistakes in a stone bathroom
- Polished stone on the floor. Beautiful and genuinely dangerous when wet. Honed, leathered or flamed finishes only, below foot level.
- Unsealed limestone or sandstone. Jaisalmer and Kota both need a penetrating sealer and periodic re-sealing. Unsealed, they absorb soap and shadow within a year.
- Plated brass instead of solid. Brass-plated zinc fittings look identical on day one and pit at the base within two years in a coastal bathroom. Ask what the body is made of.
Stone bathrooms in Mumbai flats
Three practical points. Weight: a stone bathroom is heavier than a tiled one, and in a building from the 1960s or 70s it is worth a structural opinion, particularly if the sunk slab is being deepened. Water: Mumbai's supply is hard, and it will leave scale on brass and a bloom on unsealed stone, so both need routine attention — this is a room that asks for maintenance in exchange for lasting. Ventilation: a jali ventilator only works in an external wall, and many Mumbai bathrooms are internal, sitting against a duct; in those, use a ducted exhaust on a timer and keep the jali as a screen element inside the room rather than as a ventilator. Finally, stone arrives in large pieces and needs a service lift booking and careful handling on the stair turn.

Frequently asked questions
Is Kota stone good for a bathroom floor?+
Very. Honed Kota is hard, naturally grippy when wet, cheap at ₹90–₹180 per sq ft, and it ages well. It needs sealing and it will darken slightly with use, which most people find an improvement.
Do brass fittings tarnish?+
Unlacquered brass patinates to a warm brown over a year or two and can be polished back whenever you like. PVD-coated brass holds its colour indefinitely. Brass-plated zinc, which is what most inexpensive gold-coloured fittings are, corrodes and cannot be recovered.
Can teak be used in a bathroom?+
Yes — it is one of the few timbers that suits a wet room, because of its natural oil content. Seal every cut end, keep it out of direct spray, and it will outlast the bathroom around it.
Is a jali ventilator practical in a flat?+
Only in an external wall, with an insect mesh behind it. In an internal bathroom it has no air to draw, and you still need a ducted exhaust on a run-on timer. Use the jali decoratively inside in that case.
