If you own a split-level home from the 1960s or 70s, I can almost guarantee you’re dealing with at least one 5×8 bathroom. They’re tiny, they’re dated, and they were apparently designed for a much smaller species of human. I had two of them. I completely gutted and rebuilt both, and in this guide I’m going to share everything I learned — including what I’d do differently, what it actually costs in 2026, and how to make a small bathroom feel genuinely luxurious.
How Much Does It Cost to Remodel a 5×8 Bathroom in 2026?
Let’s lead with the number everyone wants: a full DIY gut-and-rebuild of a 5×8 bathroom in 2026 realistically runs $2,500–$4,500. My original estimate of $1,500–$2,000 was accurate for 2022 but tile, cement board, and fixture costs have all increased since then. Here’s the breakdown:
| Item | Budget Option | Mid-Range Option |
|---|---|---|
| Tile (floor + shower walls) | $150–$400 | $400–$1,200 |
| Schluter/Kerdi shower system | $250–$400 | $400–$600 |
| Vanity (24” or 30”) | $200–$500 | $500–$1,500 |
| Toilet | $150–$300 | $300–$800 |
| Light fixtures | $80–$200 | $200–$600 |
| Drywall / cement board | $100–$200 | $200–$300 |
| Misc. (screws, thinset, grout, caulk) | $150–$300 | $300–$500 |
| TOTAL (DIY labor) | $1,080–$2,300 | $2,300–$5,500 |
Add 2–3x the material cost for professional labor if hiring out the full job.
Planning the Layout: The Most Important Decision You’ll Make
In a 5×8 bathroom, the layout is everything. Get it right and the space feels functional and even stylish. Get it wrong and you’ll be fighting the room every single day. The standard 5×8 layout puts the toilet on one short wall, the vanity on the long wall, and the tub/shower on the opposite short wall. That layout works — but here’s what I’d change:
Door Direction
This was my biggest mistake. I kept a standard inward-swinging door, which ate into the usable floor space and meant I had to close the door to open certain vanity drawers. If I were doing it again, I would install a pocket door — it reclaims roughly 8–10 square feet of effective space and immediately makes the room feel larger. A barn door is a cheaper alternative if a pocket door isn’t feasible.
Vanity Depth
In a 5×8, vanity depth matters more than width. A standard 21” deep vanity can create a hip-bumping hazard near the door. Look for 18” depth vanities designed specifically for small bathrooms. Wall-mounted floating vanities are the premium option — they open up the floor visually and make cleaning easier.
Walk-In Shower vs. Tub/Shower Combo
If you’re not a bath person and your home has another tub, converting to a walk-in shower is one of the best moves you can make in a 5×8. A properly sized walk-in shower along the back wall can feel surprisingly spacious, and it eliminates the shower curtain that makes the room feel smaller.

The Shower: Why the Schluter System Is Still the Right Call
I recommended the Schluter/Kerdi system in 2022 and I’m recommending it again in 2026. It remains the most reliable, installer-friendly waterproofing system available for DIY bathroom remodels. The foam boards are lightweight, the seam tape is easy to work with, and the system is comprehensively documented with video tutorials on Schluter’s YouTube channel.

- Schluter Kerdi shower kit (sized to your drain location)
- Kerdi-Board panels for shower walls (eliminates the need for cement board)
- Kerdi-Band tape for all seams and corners
- Kerdi-Drain or Kerdi-Line drain of your choice
- Schluter Ditra uncoupling membrane for floor tile (optional but highly recommended)
Shower Niches: Non-Negotiable in a Small Bathroom
In a 5×8, every inch counts. A recessed shower niche built into the back wall eliminates the need for a hanging caddy or floor-cluttering bottles. The Schluter Kerdi-Board-SN niche fits perfectly within the Kerdi system and can be tiled to match the rest of the shower. Plan your niche location before tiling — it’s much easier to build in than to add after the fact.
Tile Selection: Making a Small Space Feel Larger
The tile you choose has a bigger impact on how large the bathroom feels than almost any other decision. Here’s what works and what doesn’t in a 5×8:
- Large format tiles (12×24 or larger) on the floor create fewer grout lines, which makes the space feel bigger. Avoid small mosaic tiles on the floor — they create visual noise.
- Light colors everywhere — I went nearly all-white and it made both bathrooms feel twice the size they actually are.
- A contrasting accent tile in the shower niche or as a border adds visual interest without overwhelming the space.
- Vertical tile patterns in the shower draw the eye upward and make ceilings feel higher.
- Don’t underestimate the power of a unique tile pattern. Setting a simple white ceramic in a herringbone or offset brick pattern gives it personality without paying for expensive tile.
Storage Solutions for a 5×8 Bathroom
Storage is the constant battle in a small bathroom. Here’s what actually works:
- Recessed medicine cabinet: Replaces a flat mirror and adds 4–6 inches of storage depth without using any floor space. Easiest storage upgrade you can make.
- Over-toilet shelving: A floating shelf or ladder shelf above the toilet can hold towels, toiletries, and decorative items. Just keep it to 2–3 shelves or it feels claustrophobic.
- Towel bars on the back of the door: Adds significant towel storage without touching a single wall.
- Floating vanity with drawers: More storage than a pedestal sink and keeps floor space visible, which makes the room feel bigger.
- Built-in bench in the shower: If you have the room, a tiled shower bench adds function and visual weight that anchors the shower design.
Lighting: The Most Underrated Upgrade
Bad lighting makes a small bathroom feel like a broom closet. Good lighting can make it feel like a spa. In a 5×8, you need at minimum two light sources:
- Vanity lighting: A 3–4 light bar above (not beside) the mirror provides even, shadow-free illumination for grooming. Side-mounted sconces are ideal if you have the wall space.
- Shower lighting: A recessed shower-rated fixture directly above the shower is non-negotiable. It highlights the tilework and makes the shower feel intentional rather than like an afterthought.
Bonus: If your bathroom has no window, adding a solar tube (a small skylight-style fixture) is a game-changer and costs $300–$600 installed.
What I’d Do Differently
- Pocket door from the start — would have saved significant floor space
- Floating vanity instead of a floor-mounted one — easier to clean and visually lighter
- Plan the tile layout on paper before ordering — I ended up with cuts in awkward places that a little planning would have avoided
- Install a larger shower niche — I went with one small niche and immediately wished it was bigger
- Add a heated floor from the beginning. I added Schluter Ditra-Heat to one bathroom and not the other. The one with heated floors wins every time.
Frequently Asked Questions
How much does it cost to remodel a 5×8 bathroom in 2026?
A full DIY gut-and-rebuild runs $2,500–$4,500 in materials. Professional labor adds $5,000–$15,000 depending on your market and scope.
Do I need a permit to remodel a bathroom?
If you’re moving plumbing, adding electrical circuits, or changing the shower drain location, you’ll likely need a permit. Cosmetic work (tile, vanity swap, fixtures) typically doesn’t. Check with your local building department.
Is the Schluter Kerdi system worth it for a DIY shower?
Yes. It’s more expensive upfront than traditional cement board + membrane systems, but it’s lighter, more foolproof, and has better waterproofing performance. For a first-timer, it’s the right call.
Can I convert a tub to a walk-in shower in a 5×8 bathroom?
Absolutely — and I’d recommend it if you don’t regularly use the tub and your home has at least one other bathtub. A walk-in shower in a 5×8 feels significantly more spacious than a tub/shower combo.
