Kohler Highline Toilets

Kohler Highline toilets are a practical choice for a main bathroom, a basement washroom or a rental unit where you want a toilet that is easy to live with and easy to service. The Highline series is sold as complete one-piece and two-piece toilets and also as separate bowls and tanks, so you can buy a full set or replace just the part you need. Examples on this page include the Highline® One-piece elongated toilet, 1.28 gpf, the Highline® Two-piece round-front toilet, 1.28 gpf and the Highline® Toilet tank, 1.28 gpf.

Before you choose, measure the rough-in from the finished wall to the centre of the floor drain, and check how much room you have in front of the bowl, since elongated and round-front bowls take up different amounts of space. Think about seat height too: a taller bowl is easier for taller adults and anyone with sore knees to sit on and stand up from, while a standard height suits children and shorter users. Finish options on this page include White, Biscuit, Almond and Black Black, so you can match existing fixtures or make a change. If you are buying a bowl and tank separately, read the product details for each piece to confirm they are intended to be paired.

What to check before you buy

• Measure your rough-in first. Measure from the finished wall to the centre of the floor bolts or drain. Check the product details to confirm the toilet you choose suits that distance.
• Elongated or round-front bowl. An elongated bowl gives a bit more seating room, while a round-front bowl is a better fit in a small powder room or beside a door swing.
• Bowl height and comfort. A taller bowl is easier to rise from and is a common choice for accessible bathrooms. A standard height is often preferred where children use the toilet.
• Complete toilet or separate parts. Decide whether you need a full one-piece or two-piece toilet or just a bowl or tank to replace a damaged piece. Read the product details before pairing separate parts.
• Flush rate and water use. The flush rate is listed in the product details, and a lower figure means less water per flush. This matters in homes on a well or where water bills are a concern.

Frequently asked questions

What is the difference between a one-piece and a two-piece Highline toilet?

A one-piece toilet has the tank and bowl moulded together, which is easier to wipe down and has no seam to collect grime. A two-piece toilet has a separate tank and bowl, which makes it lighter to carry in and simpler to replace one part later.

Do Kohler Highline toilets come in colours other than white?

Yes. The finish options offered on this page include White, Biscuit, Almond and Black Black, so you can match older fixtures or choose a darker look.

Can I buy just a Highline bowl or tank?

Yes, bowls and tanks are sold separately, with examples such as the Highline® Elongated toilet bowl and the Highline® Toilet tank, 1.28 gpf. Check the product details to confirm the pieces you choose are meant to go together.
