Design for Everyone, Now and Later
Universal design means your bathroom works for a toddler, a teenager, a 40-year-old, and an 85-year-old without feeling clinical. The best time to add accessibility features is during a renovation — not when you urgently need them.
Curbless Shower: The Non-Negotiable
A curbless (zero-threshold) shower is both the most beautiful shower design and the most accessible. No step to trip over, easy for wheelchairs and walkers, and gorgeous in any style.
- Minimum size: 36″×36″ (absolute min)
- Recommended: 42″×42″ or larger
- Wheelchair accessible: 60″×36″ minimum, 60″×60″ preferred
Blocking: Do It Now, Use It Later
Install blocking (3/4″ plywood behind drywall) in shower and toilet areas during renovation. When you need grab bars later, they anchor into solid blocking — no stud hunting, no structural concerns.
- Shower: blocking from 33–36″ height on three walls
- Toilet: blocking at 33–36″ on both side walls
- Cost to add during reno: $200–$500 (labour only)
- Cost to add after (open wall, install, patch, repaint): $800–$2,500

Toilet Height: Comfort Height Makes a Difference
Standard toilets sit at 15″ seat height. “Comfort height” (ADA-compliant) toilets are 17–19″. Nearly everyone finds the taller height easier on knees and hips. Standard upgrade from $50 to $150 more than standard height.
Slip-Resistant Flooring
- Shower floor: mosaic tile (2″×2″ or 1″×1″) provides more grout lines for grip
- Bathroom floor: matte porcelain with coefficient of friction ≥ 0.50 (wet)
- Avoid: polished marble, very large smooth tiles in wet areas
Knee Clearance Under Vanity
A wall-hung vanity with 27–29″ knee clearance allows wheelchair access. Even if you don’t need it now, it’s a useful resale feature and works aesthetically as a floating vanity.
