People skip the planning stage and jump straight to picking tiles. I get it — tiles are the fun part. But a proper bathroom renovation checklist should start with the boring stuff: plumbing layout, waterproofing, and ventilation.
Skip those, and even the prettiest tiles won’t save you from a bathroom that smells damp within a year.
This checklist walks through the renovation in the order it should actually happen, not the order that’s most exciting.
Quick Answer: What’s the First Step in a Bathroom Renovation?
The first step in any bathroom renovation is assessing plumbing and waterproofing, not choosing tiles or fixtures. Fixing these foundational elements prevents leaks, mold, and expensive repairs later — issues that cost far more to fix after the tiling is done.
Step 1: Assess the Existing Plumbing
Before anything else, get a plumber to check pipes, water pressure, and drainage. Older bathrooms — especially in buildings over 15-20 years old — often have corroded pipes hiding behind the tiles.
Step 2: Plan Your Layout
Decide if you’re keeping the existing layout or moving fixtures. Keeping things where they are saves significant money on plumbing work. Moving a toilet or shower to a new spot can add ₹15,000-₹30,000 just in plumbing relocation.
Step 3: Waterproofing (Don’t Skip This)
This is the step people cut corners on most, and it’s the one that causes the most regret. Proper waterproofing on floors and up to at least 2 feet on walls prevents seepage into neighboring rooms or the floor below.
Step 4: Choose Your Fixtures
- Toilet (wall-mounted vs floor-mounted)
- Wash basin
- Shower or bathtub
- Taps and fittings
Wall-mounted toilets look sleek but cost more to install and repair. Floor-mounted units are more budget-friendly and easier to service.
Step 5: Tiles and Flooring
Pick anti-skid tiles for the floor — non-negotiable for safety, especially in homes with elderly family members. Wall tiles can be more decorative since slip resistance doesn’t matter there.
Step 6: Ventilation and Lighting
A bathroom without proper ventilation stays damp, and damp bathrooms grow mold. An exhaust fan is a small cost (₹1,500-₹3,000) that prevents a much bigger headache down the line.
Step 7: Storage
Easy to forget until you’re standing in a finished bathroom with nowhere to put your toothbrush. Plan storage — a mirror cabinet, shelves, or a vanity — before the tiling starts, not after.
Realistic Cost Ranges for a Bathroom Renovation
- Basic refresh (new fixtures, repaint, minor tile repair): ₹40,000-₹80,000
- Mid-range renovation (new tiles, fixtures, waterproofing): ₹1.2-₹2.5 lakh
- High-end renovation (premium fittings, layout change): ₹3-₹6 lakh+

Common Mistakes to Avoid
- Skipping waterproofing to save money — this almost always costs more later
- Choosing glossy floor tiles that become dangerously slippery when wet
- Underestimating how long tile work actually takes (usually 1-2 weeks alone)
- Not checking water pressure before finalizing shower fixtures
A Small Story Worth Sharing
A relative of mine renovated her bathroom and skipped waterproofing to save about ₹8,000. Eighteen months later, damp patches showed up on her neighbor’s ceiling below. The re-do, including compensation, cost her nearly ten times what she’d saved. Not every shortcut works out.
