Does a toilet waste pipe require a trap?
The toilet IS the trap. No other trap is required.

You CAN'T have a p-trap under the toilet! The p-trap is built into the toilet!
You could do that but you would need a trap to stop sewer gas from coming in. The toilet has the trap integrated into it. If you have access to underneath then you could add o…ne.
Depends on the design, but I suspect you set the seat height to the correct position and work from that, not use the waste as a height guide.
My waste pipe goes through the floor and not the wall is there a specific type of toilet i have to buy for this i have a low level toilet at the moment?
No, as long as there is a minimum of 12 inches between the centre of the drain and the back wall. The only wall hung toilets are commercial. All residential toilets run throug…h the floor.
Downstairs toilet is it ok to saddle the waste pipe from the sink onto the toilet waste pipe ontop of the insulation before floor is poured?
No, Saddles are illegal in most civilized countries
Normally local codes prevail BUT I normally go no more then 24" from the trap and the trap located no more then 2ft from the vent
The short answer is yes, but like all answers comes with conditions. In a traditional residential plumbing system all drain lines eventually connect together, everything is in…terconnected. The long answer is that connecting fixtures to a drain system must follow certain rules and good practices which have been proven over time. Assuming you have a rudimentary knowledge of plumbing systems you may proceed with the following. You may connect to your horizontal toilet waste pipe but should be 3-5 pipe diameters downstream any vertical portion (like where it turns up to the toilet, or turns to go up a wall for an upstairs toilet.) If you do connect to a horizontal portion the new pipe must be sized to serve as both a drain (for the new fixture) and as a vent (for both the new fixture and the toilet.) this means that the new drain must connect back into the vent system (at least 6" higher than the rim of the highest fixture connecting to that system) OR must vent separately out the roof of the building or through an approved air admittance device. (basically an air valve in the cabinet or wall space that lets air into the system but not out. - -air valves have special provisions and are tricky so research them thoroughly before installing one.) You may also connect to a vertical stack. (a large pipe serving fixtures on the floor above) When connecting to a stack you need only size the new pipe to serve as a drain and vent for the new fixture. Generally you may connect to any portion of the vertical stack (high or low) as long as you use a wye branch fitting or other approved drainage pattern fitting. hope this helps.
The trap in your toilet is the " U" shaped pipe that supposedly catches all of the germs. It is also found on sinks.
The bend in the pipe can be ignored as long as the drain is even at the floor. The pipe can be coming out of the floor at an angle and it will still work. Cut the pip flush wi…th the floor and use a metal floor flange screwed down to the floor. The flange and the pipe do not need to be joined together, the wax ring will make the connection.
The easiest solution would be to move the toilet so that it lines up with the waste pipe.
Yes, unless urinal has an integral trap.
1/8 to 1/4 inch drop per foot of length.
