Can You DIY a Bathroom Remodel?
A bathroom remodel has a wide DIY range. Cosmetic work — vanity swaps, faucet replacement, paint, mirror, light fixtures — is beginner territory. A full gut-to-studs remodel with tiling, plumbing moves, and new shower — that's advanced. Know which version you're taking on before you start.
What You'll Need
Skills
- •Tile setting: mixing thinset, layout, cutting tile, grouting
- •Basic plumbing: shutting off water, connecting supply lines and drains
- •Waterproofing knowledge — critical in wet areas
- •Drywall hanging and finishing
- •Comfort working in a tight space
Tools
- •Tile saw (wet saw — rent for the job)
- •Notched trowel and grout float
- •Level and tile spacers
- •Drill and hole saw (for plumbing cutouts)
- •Oscillating multi-tool (invaluable for undercutting door frames and trim)
- •Shop vac
- •Caulk gun
Step-by-Step Overview
Remove fixtures, vanity, toilet, and old tile. Inspect the subfloor and wall framing for moisture damage or rot — address any issues before closing walls back up.
If you're moving a drain or supply line, this is the hardest part and often worth hiring a plumber for. New fixture locations must be permitted and inspected.
Use cement board (Hardiebacker or Durock) on all shower and tub surround walls. Tape seams with alkali-resistant mesh tape and thinset. Apply a waterproofing membrane over seams and corners — Redgard or Schluter Kerdi are popular.
Layout your tile dry first to plan the pattern and avoid slivers at edges. Use a notched trowel to spread thinset, set tiles with spacers, and check level frequently. Back-butter large tiles.
Set the valve body rough-in to manufacturer-specified depth before tile. Install the shower door or curtain rod after tile.
Set the vanity, connect supply lines, and caulk around the base. Install the toilet with a new wax ring. Hang mirrors and towel bars last.
Grout tile joints, wipe clean, and let cure. Caulk all inside corners and the tub/shower-to-floor joint — never grout these, they will crack. Touch up paint and reinstall trim.
Potential Savings
For a typical 60 sq ft bathroom remodel at the national midrange cost of $16,500, doing it yourself could save roughly $4,950–$8,250 in labor costs. Materials remain similar either way.
Actual savings depend on your region, skill level, and whether you need to rent specialized equipment.
Pro Tips
- Buy 15% extra tile — tile dye lots vary and matching after the fact is frustrating
- Niche shelves in showers need to be waterproofed as carefully as the floor — they fail often
- A linear drain makes shower floor tile layout much easier (no need to slope four directions)
- Caulk all inside corners and transitions to the floor — tile grout cracks at these joints
Watch Out For
- ⚠Improperly waterproofed shower walls are the #1 cause of hidden moisture damage and mold — don't cut corners here
- ⚠Most jurisdictions require a permit to move plumbing. Unpermitted work can affect your home sale
When to Call a Pro Instead
- →Moving drain lines — cutting concrete slab is not a beginner task
- →Any gas line work
- →Electrical work beyond simple fixture swaps (GFCI outlets near water always require inspection)
- →If you find significant mold or rot after demo — stopping to remediate properly is critical
