Understanding Small Bathroom Layouts

Before diving into specific ideas, let’s establish what we’re working with:

Bathroom Size Dimensions What Fits
Powder Room 15-25 sq ft Toilet + pedestal sink
Three-Quarter 35-45 sq ft Toilet + sink + shower
Full (Small) 45-55 sq ft Toilet + sink + tub/shower
Full (Standard) 55-75 sq ft All fixtures with some breathing room

Most “small” bathrooms fall in the 35-55 square foot range. These ideas are optimized for that sweet spot.

Space-Saving Fixtures

1. Floating Vanity

A wall-mounted vanity creates the illusion of more floor space and makes cleaning easier. The visual continuity of visible floor tricks your eye into perceiving a larger room.

Tier Product Price Best For
Budget DERA Wall Mounted 24" $289 Powder rooms
Mid-Range Glacier Bay Huckleberry 30" $549 Most bathrooms
Premium Kohler Jute 36" $1,200+ Master baths

Installation Tip: Floating vanities require blocking in the wall for support. Plan this during rough-in if you’re doing a gut renovation.

2. Corner Sink

Tucking your sink into a corner opens up valuable wall space and improves traffic flow.

Recommended:

3. Compact Toilets

Standard toilets project 28-30” from the wall. Compact models reduce that to 24-26”, reclaiming precious inches.

Type Product Price Space Saved
Elongated Compact TOTO Drake Compact $348 2-3 inches
Round Bowl American Standard Cadet $199 2 inches
Wall-Hung Duravit Starck 3 + carrier $1,050 8-10 inches

4. Narrow-Depth Vanity

Standard vanity depth is 21”. Narrow options at 16-18” still function well while opening up the room.

Options:

5. Curbless/Walk-In Shower

Eliminating the shower curb creates a seamless floor that makes the entire bathroom feel larger.

Linear Drain Price Best For
Neodrain 24" $89 Budget-friendly option
QuARTz by ACO $200-400 European engineering
Schluter Kerdi-Line $300+ Integrated waterproofing

Storage Solutions

6. Recessed Medicine Cabinet

Build your storage INTO the wall rather than projecting from it.

Product Size Price Special Features
Kohler Recessed 20" x 26" $175 Adjustable shelves
Robern R3 Series 30" $600 Defogger available
Krugg Svange 24" $350 Built-in outlets & USB

7. Over-Toilet Storage

The 24” above your toilet is prime real estate. Use it.

Options:

8. Shower Niche

Built-in recessed shelves eliminate the need for hanging caddies.

Sizing Guidelines:

  • Horizontal niche: 12” x 4” minimum per shelf
  • Vertical niche: 4” x 14” for bottles
  • Multiple niches better than one large one

Pre-Formed Options:

Visual Expansion Tricks

9. Large-Format Tiles

Fewer grout lines = less visual clutter = bigger-feeling space. Use 12x24” or larger tiles.

Product Price/Sq Ft Look
MSI Aria Ice $2.50 Marble look, porcelain
Della Torre Carrara $3.00 Classic veining
Emser Paladino $6.00 Limestone look, premium

10. Clear Glass Shower Enclosure

Frosted glass stops sightlines and makes the room feel smaller. Clear glass lets the eye travel freely.

Tier Option Price
Budget DreamLine Enigma-X $700-900
Mid-Range Kohler Composed $1,200-1,800
Custom Local glass shop $1,500-3,000

11. Light Colors & Large Mirrors

White, cream, soft gray, and pale blue reflect light and make spaces feel airy.

  • Benjamin Moore “Simply White” OC-117 - Warm, versatile
  • Sherwin-Williams “Agreeable Gray” SW7029 - Popular neutral
  • Farrow & Ball “Pointing” - Elegant off-white
