How to find the right Toilet Bowls AI guide

What the AI looks for in Toilet Bowls

Tank compatibility
Buy a bowl that the manufacturer lists as matching your exact tank model. Bolt spacing, gasket type, and flush design differ between models, even within the same brand.
Rough-in
Match the bowl to your measured rough-in: 10, 12, or 14 inches. The bowl's outlet position decides whether it fits against your wall.
Shape and height
Elongated or round, and standard or chair height, must match your seat and your space. These choices affect comfort and which seats will fit.
Color match
Use the same brand's named color as your tank. Off-white shades such as biscuit and bone vary between brands.

Brands that matter

  • TOTO: Sells bowls separately for many of its two-piece models.
  • Kohler: Many bowls are sold separately and listed by matching tank.
  • American Standard: Bowl and tank pairings are clearly listed.
  • Gerber: Offers separate bowls for its two-piece lines.

What to avoid

  • Mixing a bowl and tank from different brands
  • Buying a bowl without confirming its rough-in

Questions

Why is the bowl sold without a tank?

Two-piece toilets are often sold as two boxes, so you must order the matching tank as well.
