You need a large water pipe to feed the toilet--1" in most cases----the toilets are not terribly expensive---the Sloan flush valves will set you back as much as a cheap toilet,however.


Call a local plumbing supply house----do not attempt this with 1/2" feed lines---

Do you have a link?

Just curious, is it really tankless, or is it a hidden or wall-hung toilet?
Here's a link, if the mods don't mind.

You need to check your supply. You can do it with 1/2 inch if everything is right.
This from Dexterton toilets:

Quote:
Required water pressure:
0.15 MPa (21.33 PSI) ~ 0.75 MPa (106.67 PSI)

Water volume flow rate:

Use the following method to determine the water volume flow rate.
1. Prepare a bucket.
2. Let water out for 10 seconds to check the flow.
3. When water supply of 5.5 L or up is reached within 10 seconds (8.72 gallons per minute), then required water volume is secured.

NOTE : The most ideal diameter of the water supply pipe is 1 inch.
A 1/2 inch water supply pipe can be used provided that the required water volume (5.5L in 10 seconds) is acquired.

The tankless toilet that works with a 1" flushvalve does not take less floor space- well maybe 2"- but your water pipe sizing will need an upgrade to meet water fixture unit code requirements
There are wall hung residential toilets as well...
