Fitment Guide:
Is My Toilet Compatible?

Do bidet attachments work on any toilet?

Almost all standard two-piece toilets are compatible. For one-piece toilets, check for clearance behind the seat.

What if I choose the wrong fit?

Don’t worry—we offer hassle-free returns and exchanges so you can get the right model.

One-Piece or Two-Piece: Spotting the Difference

Two-Piece Toilet

The most common residential style toilet. If you have one, great! Our Alpha Bidets will fit.

One-Piece Toilet

The tank and bowl are molded into a seamless unit. If you have one, check the Special Cases section below.

“The warm water and heated seat are absolute game-changers. 
I can’t imagine going back to toilet paper!”

Measuring Your Bowl: Elongated or Round?

Measuring Your Bowl: Elongated or Round?

  1. The JX2, iX Pure and UX Pearl models need just 1.5" of clearance, while the GX Wave needs at least 1.75".

  2. 5.5" is standard (required by the JX2). The UX Pearl, iX Pure, and GX/GXR Wave work with anything between 5"–7".

  3. Bowl sizes are usually 18.5" for elongated and about 16.5" for round (measured from the bolts).

For Those Unique Cases…

One-Piece Toilet, No Curve

If your 1 piece toilet's tank meets the bowl at close to a 90 degree angle, then it's compatible.

Examples
  • Kohler Memoirs (pictured)
  • TOTO Ultramax & Supreme
  • Woodbridge T-0001

One-Piece Toilet, French Curve

If your 1 piece toilet has a tank where the sides curve forward, then it MAY NOT be compatible. Contact us for more details.

Examples
  • Kohler San Raphael (pictured) only JX fits
  • Kohler San Souci JX and ONE fit
  • Kohler Rialto (not compatible)

Compact Elongated Toilet

Some elongated toilets have a more compact bowl and not full size. We'd recommend the UX Pearl or iX Pure for best results, but the JX2 also works.

Examples
  • Kohler Santa Rosa (pictured)
  • American Standard Compact Cadet 3

Skirted Toilet

Skirted toilets have a concealed trapway for easy cleaning. They are usually compatible with Alpha Bidets, but may require extra installation parts.

Examples
  • Kohler Salle (pictured)
  • TOTO Aquia
