Bathroom Renovation Cost Per Sq Ft in India

Most people ask, "how much does it cost to renovate a bathroom in India?" The honest answer is that it depends on three things: the size, the quality of materials and how much hidden work (plumbing, waterproofing, wall repair) is needed once the old tiles come off. Here is a realistic range.

What is included in the price?

A proper quote should cover demolition and debris removal, waterproofing, plumbing and electrical changes, wall and floor tiles, sanitaryware (toilet, wash basin), CP fittings (taps, shower, health faucet), accessories, and finishing. Always ask for an itemised quote so you can compare two contractors fairly.

What makes bathroom renovation cost go up?

• Changing the layout or shifting the toilet or drain position
• Replacing old GI or CPVC pipes hidden in the walls
• Large-format or imported tiles
• Wall-hung toilets, rain showers, and smart or heated fixtures
• Repairing seepage, damp walls or structural cracks found after demolition

How can I reduce bathroom renovation cost without losing quality?

Spend on what is hidden (waterproofing, plumbing) and save on what is visible. Choose mid-range tiles from reputed brands, keep the existing drain position, use a good wall-mounted or floor-mounted toilet instead of a concealed system, and pick one feature wall instead of tiling everything with premium tiles.

Our Bathroom Renovation Services

Complete bathroom renovation and remodeling

We strip the bathroom down, fix the base, and rebuild it with new waterproofing, plumbing, tiles and fittings. This is the right choice when the bathroom is more than 10 to 15 years old, has leakage, or the layout does not work for your family anymore.

Small bathroom renovation

Compact bathrooms in apartments need smart planning more than big budgets. We optimise the space with corner shelves, niche storage, glass partitions and lighter colours so a small bathroom feels bigger and stays dry.

Luxury bathroom renovation

Rain showers, freestanding or built-in bathtubs, backlit mirrors, wall-hung toilets, vanity units and designer tiles. We design the look, source the materials and manage the installation.

Bathroom waterproofing and leakage repair

Damp patches on the outside wall or the ceiling below usually mean the waterproofing has failed. We test, treat and re-waterproof floors and wet walls with proven coatings and a flood test before tiling.

Bathroom tiles and flooring replacement

Anti-skid floor tiles, glossy or matt wall tiles, and mosaic or feature walls. We handle removal, levelling, laying and grouting with epoxy grout where needed.

Sanitaryware, CP fittings and plumbing

Installation of toilets, wash basins, showers, mixers, geysers, exhaust fans and concealed plumbing, including replacement of old pipes.

Elderly-friendly and accessible bathrooms

Grab bars, non-slip flooring, walk-in showers, higher toilet seats and better lighting for safer daily use at home.

Our Bathroom Renovation Process, Step by Step

1. Free site visit and measurement. We check the size, existing plumbing, drainage and moisture problems.
2. Design and material selection. You choose tiles, fittings and layout. We suggest options that suit your budget.
3. Itemised quotation. Every material and labour cost is written down before work starts.
4. Demolition and debris removal. Old tiles, fixtures and screed are removed carefully to limit dust and noise.
5. Plumbing and electrical rework. New pipes, drainage slopes, concealed fittings and points for light, geyser and exhaust.
6. Waterproofing and flood test. Water is held on the floor for 24 to 48 hours to confirm there is no leakage.
7. Tiling and grouting. Floor slope towards the drain, straight lines, tight joints.
8. Sanitaryware and fittings installation. Toilet, basin, shower, mixer, accessories and mirror.
9. Final cleaning and handover. We test every tap, flush and drain with you before we call it complete.

How Long Does a Bathroom Renovation Take?

A typical bathroom renovation takes 7 to 14 days. A quick refresh (new fittings and a paint or tile touch-up) can be done in 3 to 5 days. Larger bathrooms, layout changes and imported materials can take 3 weeks.

The biggest delays come from materials arriving late and problems discovered behind old walls. Choosing tiles and fittings before demolition starts avoids most of this.

Bathroom Waterproofing: The Step You Cannot Skip

Waterproofing is the part of a bathroom renovation that nobody sees, and the part that causes most complaints later. Poor waterproofing leads to damp walls in the next room, peeling paint, mould and leakage to the flat below. Fixing it after tiles are laid means breaking everything again.

How is a bathroom properly waterproofed?

• Clean the surface and seal all joints, pipe openings and corners
• Apply a cementitious or polyurethane waterproofing coating on the floor and up the walls (at least 1 to 2 feet, and up to full height around the shower)
• Allow proper curing time
• Do a flood test for 24 to 48 hours before tiling

Can I renovate my bathroom without waterproofing?

You can, but it is a false saving. A leak repair later can cost more than the waterproofing itself, plus the cost of redoing tiles. We recommend waterproofing in every full renovation.

Tiles, Fittings and Sanitaryware: What to Choose

Which tiles are best for a bathroom?

For floors, choose anti-skid matt tiles (vitrified or ceramic) with a good grip rating. For walls, glossy or matt ceramic and porcelain tiles are easy to clean. Light colours make small bathrooms look larger, while a dark or textured feature wall behind the shower or vanity adds style without a big budget.

Wall-hung or floor-mounted toilet?

Wall-hung toilets look clean, are easy to mop under and save visual space, but need a concealed cistern and a strong wall, so they cost more. Floor-mounted toilets are cheaper, simple to repair and perfectly fine for most homes.

Which CP fittings last longest?

Choose fittings from established brands with brass bodies and a solid warranty. Cheap plated fittings tend to corrode and leak within a couple of years, especially in hard-water areas.

Shower enclosure or curtain?

Toughened glass partitions keep the floor dry, look premium and are easy to clean. A curtain is the budget choice. In small bathrooms, a fixed glass panel is often enough.

Small Bathroom Renovation Ideas That Actually Work

• Use light-coloured large tiles to reduce joints and make the space feel wider
• Replace a bulky vanity with a wall-mounted basin and a mirror cabinet
• Add niche shelves inside the wall instead of stand-alone racks
• Choose a glass partition instead of a curtain for an open look
• Install good lighting: a bright ceiling light plus a mirror light
• Fit an exhaust fan to control moisture and odour
• Keep the layout simple; moving the toilet or drain is where costs increase

Common Bathroom Renovation Mistakes to Avoid

• Skipping waterproofing or the flood test. The most expensive mistake you can make.
• Choosing the lowest quote without comparing scope. A cheap quote often leaves out plumbing, debris removal or waterproofing.
• Ignoring floor slope. Water must flow to the drain, not collect near the door.
• Buying tiles without extra quantity. Order 8 to 10% extra for cuts and breakage.
• Poor ventilation. Without an exhaust fan, moisture spoils paint, ceilings and fittings.
• Changing decisions mid-work. Late changes cause delay and extra cost.

How to Choose a Bathroom Renovation Contractor

When you search for a bathroom renovation contractor near me, the choice is huge. These questions separate a reliable team from a risky one.

1. Can I see photos or visit a completed bathroom?
2. Is the quote itemised, with brand names and specifications?
3. What waterproofing method do you use, and is there a written warranty?
4. Who does the plumbing, tiling and electrical: your own team or unknown subcontractors?
5. How is payment linked to progress?
6. Who is responsible for clearing debris?

At Kartik Renovation, one team handles design, waterproofing, plumbing, tiling and finishing, so accountability stays in one place.
