Toilet Dilemma


I am looking for a toilet for a new small bathroom (8'x4'). The floor is concrete, undergrounds already placed.

It needs to sit between a 36" deep shower and and a 25" vanity. The 4" black pipe (ABS, not cast iron) toilet line is a bit close to the shower (a 20" wide tank would be 1" from the shower pan, a bit further from the glass shower doors).

My choices are to put in an offset flange or find a toilet with a smaller tank.

1. Does a 2 or 3" offset flange hinder flushing or make the toilet more 'clog-prone'? The ones I've seen are plastic ABS with a metal ring on top, the bottom fitting inside the 4" pipe. Also, even a 2" offset flange seems to significantly reduce the inner diameter prior to hitting the 4" drain.

2. If the offset flange isn't the way to go (and I think I much prefer a high quality, well flushing small-tank toilet ), can someone recommend a quality, good flushing toilet that isn't as wide?(in the range of $300 or less).

I've been checking out Toto, as they have such a good reputation, but the 1.6 GPFs all seem to have 19.5" tanks. There is a high efficiency 1.28 GPF that is 14.5" wide, but I worry about the flush efficiency (50 reviews for a 5 star rating).

That particular model is:

TOTO CST454CEFG Drake II Two Piece High Efficiency Toilet (HET) Sanagloss

It's at Homeclick.com and at the top of my budget, but 14.5" sounds pretty good if it has the attributes I'm looking for, which include a large and fully glazed trapway, large flush valve...well, you get the idea.

So, what would the experts recommend? Offset flange or small tank toilet? And if the latter, recommendations are greatly appreciated!

Thanks,
Mark

Toilet Dilemma


The problem is elbow room,not tank size-----

If this is an inspected job ---open the floor and move the opening---I don't care for the offset flanges

they are designed to clear a floor joist so no cutting is needed.

With concrete if you make the hole large enough you should be able to move the opening without the offset.

Toilet Dilemma


What are the measurements of the centerline of the toilet pipe when measured from the back wall and side wall?

After seeing one, I agree!

Thanks!

You need more space for the toilet----

Opening the floor is the only way I know of to do it.

Basement floors are 4" thick typically and may have mesh but seldom use rebar.

You need 15" from the centerline of the toilet to a vanity or tub, minimum. More when you have other considerations, like a shower. Imagine how narrow your opening to get into the shower will be when the door is hitting the toilet. Get a skinny pedistal sink and jam it tight to the wall with the door. Move the toilet stub as far as you can the same direction.

Thanks to both of you for the heads up. I'm trying to decide the best course of action now. The slab it's sitting on is not in the basement, but is part of the main house slab and is thick and reinforced. I'm considering a shorter shower pan, which may mean going with cultured marble. Thanks, and any other suggestions or comments welcome.

Toilet Dilemma


Can the back wall of the shower be moved?

A custom pan is a bit of work but might be the answer to the shower drain location.

Building a shower pan with pre-sloped mortar bed, liner and curb.

The back wall is an outer wall, bricked outside.

Thanks for the link, but If I go with a custom pan, I'll likely let someone pour cultured marble.

I have, however, thought of a possilbe simple solution......extend the hole around the drain (going down 5" or 6" deep), use two 22 degree fittings (one normal, one street) and a little bit of 4" pipe.
