Buying Guide

There are several things you should know before going out to get a toilet. It is one thing if you need a toilet for a residential apartment, and it is another thing if you need it for a commercial space. The best thing to do is to visit a toilet showroom whenever you want to buy or if you can’t visit a showroom, you should get references. Some of the things you should consider include:


While you should not be tight-handed when planning to buy a toilet, you should be aware of what you can afford. It is possible that you see a very lovely toilet that you want, but you might not be able to afford it. If the features of that particular toilet are not really necessary, you should go for a cheaper one

Flush Mechanism

There are different types of flush mechanisms out there; we have the dual flush and the more traditional one. The dual flush is usually a great way to conserve water and contribute to environmental conservation. The dual flush is usually an excellent toilet to buy, as you can save more money by using less water.

The only thing is that they are typically more expensive than the traditional ones. If you can afford it, however, you should go for it. Another thing with the flush mechanism is that you should check if a toilet comes with a flush lever or button, whichever one you feel comfortable using is the one you should go for.


The height of any toilet seat will positively affect the comfort you get from using it. Although there is a universal height, you have to be more specific when getting a toilet for yourself, especially if you have a peculiar condition, for example, a knee problem. If a toilet seat is too low, you can find it hard to stand up once you sit and if it is too high, you will not be comfortable.
