How to Choose The Best One-Piece Toilet
Chances are you are thinking about a clean look for your one-piece toilet- that’s why you’re choosing it in the first place.
One-piece toilets offer the easiest to clean design and will appear clean longer, because the lack of a seam means that there is nowhere for dust, dirt, and mildew to accumulate and grow.
Since you are concerned about cleanliness, you will want a toilet that packs more stay clean power than just a lack of a seam.
Toilets by Toto and American Standard feature special coatings designed to resist staining, mildew, and mold.
Some surfaces are antimicrobial while others are super slick to prevent anything from sticking to them.
Toilets made of vitreous china resist scratches, acid damage, and discoloration.
Toilets that offer a skirted design hide the exposed plumbing on the base of the toilet, keeping dust from settling and allowing you to clean the base with one smooth stroke.
Some people find that skirting looks less attractive and traditional than toilets with exposed tubing, and skirting that sticks out to far under the seat can take up foot room and make seating uncomfortable as your legs rub against the base.
Some one-piece toilets come with everything included, and feature lids and seats that close slowly to stop you from every slamming the seat.
Other toilets require you to buy the hardware and seat separately. Take into account the price of the toilet and everything else you will need to purchase when comparing toilets.
A bowl clearing flush is one of the most important features in any toilet, but you don’t want to waste water either.
Some toilets will power anything out of the bowl with their wider flush valves and trapways that allow more water to enter the bowl at a time, so a more powerful flush is accomplished using less water.
Other toilets offer dual flushes so you can use as much water as you need, dropping your water usage considerably.
