Find the Ideal One-Piece Toilet for Your Washroom
You should test, compare, and evaluate the different toilets on the market so that you can get the best one for your lavatory. With that said, here are a few things that you can look out for:
Effective Flushing Toilet
There is a huge difference in flushing ability of one toilet and another – across models and brands. To see how the toilet will react, you can put in some sponges or baby wipes in the bowl to see whether it is likely to clog. You should also determine how the flush will clean your toilet bowl and carry the waste down your drain line.
The top performing models leave the bowl unscratched and carry the material far down the drain pipe, minimizing the risk of clogging.
More water used or flushed means a cleaner toilet (but it isn’t always true). But toilets use about 30% of all home water, so it is not a surprise that the government has set standards for toilets to conserve water.
For instance, the recommended gallons per flush are 1.6 gallons. The one-piece toilet you intend to buy should meet this condition or even be lower. Most models come with 1.28 gallons per flush ability which is sufficient to clean your toilet completely.
Models that are efficient often carry a watersense label. So, watch out for it when buying your unit.
Right Size Toilet
You should always narrow your choices by ensuring that the toilet you buy matches your current toilet rough-in dimensions – that’s the distance from the center of the flange to the wall.
A measurement of about 12-inch is standard, but 14-inch and 10-inch models are also found on the market. Also, a comfortable height of about 19”, plus or minus 2 inches, is also recommended. This height ensures that you get on and off your toilet with ease.
