Lowes toilet/installation package is best choice

Would Recommend

I like the height. I wish the seat were softer. I few days after installation, the installer returned because my bathroom floor flooded because there was a bolt that had loosened, but it was quickly resolved. The installer (Scott?) was a pleasure both times he showed up.

Toilet ok, but kit leaves a bit to desired

Would Recommend

Toilet is fine, seems good quality. But…the valve has zero adjustment for water height, and it fills to within about 1/8” of the top of the overflow tube. No room for error or float decay. Also, the wax ring included you can just throw away. Just be sure to buy one with a flange before you leave so that you have a decent one to install with the toilet. Seat is a slow close, but the hinges don’t come with any adhesive to help it from twisting over time (usually a decent seat comes with some ...

The best flush and refill!

Would Recommend

We purchased three (3) of these toilets and we love them. We joke about how weird we are that we are so excited about toilets! We replaced ours which were at least 30 years old. The best thing is how well and quickly they flush and refill. It’s kind of like a miracle. Lol
