It all depends on your taste.
Difference between 1 or 2 piece toilet.
A one piece toilet is a single unit where the tank and bowl are attached without any joints.
A two piece toilet is a toilet design where the tank and bowl are sold separately and joined using fittings.
Both have the same flushing technology.
The common two piece toilet consists of a separate tank and bowl whereas the one piece toilet will have the tank molded with the bowl as one whole unit.
A two piece toilet weighs about 55 pounds while a one piece toilet weighs around 88 pounds.
You can tell the difference by looking at the joint between the tank and the bowl.
These are the most commonly found toilets in the market.
All in all there is no significant difference between a one piece and two piece toilet.
Installation for each toilet costs around 100.
Besides one piece toilet will not take much space since the tank is joined to the bowl.
However a one piece toilet offers more comfort and is easier to maintain than a two piece toilet.
In general one piece toilets range from 400 1 200 while a two piece toilet might range from 150 to 600.
Also they look more beautiful as they have the tank and bowl seamlessly integrated into a one piece.
So a one piece toilet will cost between 500 and 1 300 with installation while the two piece costs between 250 and 700.
