Step-by-Step: DIY Bathroom Remodel

Step 1: Plan Your Bathroom Remodel

Start by deciding what you want to achieve:

Are you doing a cosmetic update or a complete renovation?
Will you change the layout or keep it the same?
What is your budget and timeline?

Design Ideas:

Install a walk-in shower

Step 2: Set Your Budget

Your DIY bathroom remodel budget should include the following:

Tool rental (if needed)
Emergency cushion (10–15% for surprises)

Average DIY Remodel Cost:

Small bathroom: $1,000–$3,500

Mid-range remodel: $4,000–$7,500

Luxury DIY remodel: $8,000+

Saving Tip: Refurbish your current vanity or repaint cabinets to cut costs.

Step 3: Demolish the Old Bathroom

Time to roll up your sleeves! Start by turning off the water supply and electricity.

What to Remove:

Old tile and flooring
Vanity and countertop
Toilet (if replacing)
Shower or tub (if needed)
Light fixtures and mirrors

Demolition Tips:

Remove baseboards carefully so they can be reused
Use a utility knife to cut through caulk and sealants
Be cautious of pipes and wires inside walls

Wear safety gear—especially during tile or drywall removal.

Step 4: Address Plumbing and Electrical

This step depends on whether you’re moving fixtures or just upgrading them.

Plumbing Tasks:

Relocate drain lines or supply pipes
Install shut-off valves
Prep for a new sink, toilet, or tub

Electrical Tasks:

Move or install GFCI outlets
Add vanity lighting or wall sconces
Install an exhaust fan for ventilation

Pro Tip: If you’re unsure, hire a licensed plumber or electrician just for this phase—it’s worth the peace of mind.

Step 5: Install New Fixtures

Start putting your new bathroom together.

Installation Order:

Shower or Bathtub: Install tub or shower base, followed by tile or panels
Drywall or Cement Board: Replace damaged areas, use moisture-resistant boards in wet zones
Flooring: Install tile, vinyl plank, or waterproof laminate
Vanity and Sink: Secure vanity and connect plumbing
Toilet: Set the new toilet in place using a new wax ring
Lighting and Mirrors: Install updated lighting, mirror, and any accessories

Seal everything correctly to prevent leaks or mold.

Step 6: Tile and Paint

Wall Tiling Tips:

Use spacers for even grout lines
Apply waterproofing membrane behind wet area tiles
Grout and seal all joints after the tiles are set

Painting Tips:

Choose moisture-resistant paint (satin or semi-gloss finish)
Use painter’s tape to protect trim and fixtures
Apply two coats for the best coverage

Color Idea: Light colors make small bathrooms look bigger and more inviting.

Step 7: Add Storage and Accessories

No bathroom is complete without smart storage and finishing touches:

Storage Ideas:

Floating shelves above the toilet
Built-in niches in the shower
Over-the-door organizers
Under-sink drawers or baskets

Accessories:
