Dual Flush Toilets – Things To Consider

Buying the best dual flush toilet isn’t easy. You need to consider some factors.

Some of the things to consider in choosing a dual flush toilet are:

1. Toilet bowl type

You can choose between a one piece or two piece toilet bowl. The one piece toilet bowl is easier to clean, and is a smart choice for your small bathrooms. But it can be very expensive.

2. Toilet seat type

Choose between a round or an elongated front bowl. The round toilet seat is not as comfortable as the elongated toilet seat, though.

3. Usage of water

Since you are looking at dual flush toilets, it is already a given that you will be able to save lots of water.

But you don’t want to compromise on flushing power as well because the last thing you want to happen is to deal with solid waste that won’t go down the drain.

4. Bidets

If you can get a dual flush toilet that accommodates bidet seat, the better. Bidet toilet seats are deemed to be a hygienic choice for most households.
