Wall hung toilet set inc fixings advice required.

UnsureAboutthis

We are getting a new bathroom fitted.

For one reason or another, we have decided to go for the above toilet/etc.

Looking at frames for these toilets I've worked out the best frames
could be Ghore and Grohe and Giberit IIRC.

Having visited two well-known DIY stores, judging by what the store workers were saying, by all accounts they knew less about the frames and the compatibility between different toilets.

You can get a set, ie toilet pan and frame/etc but choice is limmited.

Looking at many online sites, some are better than others with their diagrams.

In our bathroom, we are limited to the maximum height of the frame as the window sill/shelf is 1050mm.  Most frames are 1150mm. The frames are however adjustable in height but none of the sites I've read give a minimum height of frame which will have to be about  25mm lower than the window shelt to accommodate the casing and tiles/glue etc.

We also need a toilet height of 420mm this is what we have ATM including the seat height.

Next week my wife and I are hoping to visit bathroom specialist stores that appear to have at least a dozen bathrooms on display in the hope that they can advise us what height of frame we need, ie the frame allows us to reduce the total height below the window shelf. Then still be able to get 420mm to the top of the toilet inc seat with a max of plus of minus 5mm, EG, absolute min height 415 and max height 425mm to the top of the seat

I've noted the widths of frames are often 500mm and min depth varies from 125mm to 350mm ideally 250mm depth max.

I'd be grateful for any help you can give.

Max budget 500 for frame and seat but ideally 300

I've read the two wall-hung kits I've mention above are quieter.
I've noted that different frames have different min and mx water flushes

I've also learned that we do NOT want the push tabs to flush the toilet hidden be the seat cover when that is up. Yes, there are one or two top flush toilets but not many.

We have wall hung toilets with built in cisterns - I'd say from experience that having the flush buttons behind the lid when it is raised forces you to close the lid before flushing - this is much more hygienic. 

What's your objection to this arrangement?

This.  Me too, I much prefer it now.  

The flush plate also acts as access to be able to mend anything inside the cistern.  

OP, you are best off speaking to the manufacturer's technical department to get proper advice on their specific products.

I'm aware of almost everything other than the questions I've asked. Please help if you can.

You've got a clear idea of the height of the toilet seat, however there's something else you might want to consider... When we re did our shower room,  we partly decided on the height of the bowl to allow easy access for vacuuming underneath.

Before the refurb of our shower room the other bathroom had a wall mounted toilet slightly higher than the wall mounted toilet in the shower room. This left a bigger space underneath which made cleaning (particularly vacuuming) much easier. 

When the shower room was refurbished, we ensured the replacement wall hung toilet was at a height allowing easy vacuuming. It's a small thing at the point of installation, but a total pain when you're living with it.

I think Doozergirl has given you great advice - if you have specific questions as to whether something will fit / work in your exact bathroom you should contact the manufacturers

Grohe do a low framed height version.

Thank you. I am very particular regarding the WHB higher and as it is in a large 850mm unit/basin x 600 IIRC, there will be plenty of room under it. The two wall cupboards are to be wall-hung for the same reasons. The toilet pan will ideally be flat-based, ensuring it is easier to clean. I'm also particular about the distances from a wall to the right side as we want good elbow clearance. We are also fitting a shaped chrome rail within the shower as we did in our last place some 35 years ago.. We also ensure the towel rail CH pipes are now cut into the wall.

We are not going for a shower enclosure but a big panel down most of the length and 1/3 the width panel. This IMO will be much easier to clean and look neater. I'm also investigating a ceiling extractor as I've read they extract more air than wall fits and this will above the shower tray that is 1400 x 900mm

We've also decided to have a small hook for a towel right next to the tray and two, very sturdy soap holders over the basin.
Withing the shower, we've decided for those cut-outs where we coan place shampoo etc., heights and positions to be determined nearer the time

The shower tray will have to be stone/resin and I'm investigating the slip restience aesthetics of trays.

I'm seriously stuck on the wall-hung frame/wc. Thanks.

Thanks I've already seen this and am unsure about the toilet heights, ie ensure the toilet to the top of the seat is ideally 420mm plus or minus 5mm.

What are you trying to work out? You can set the height of the toilet to whatever height you want. If you lower the frame you lower the height of the toilet. So there won’t be a minimum height you can set them. I would have thought the height of the frame being 1150 is set for a standard toilet height. Lower it and your toilet will be too low. 

The only difference between different manufacturers of toilets is the bolt centres. The above link to the grohe frame has holes for both types, so you can use any wall hung toilet. 

  The only thing is I would stick to the same manufacturer of flush plate to the frame. I have a Villeroy & boch frame with a Duravit toilet, but you can only use the Villeroy & Boch flush plate with their frames.

Probably I did not make my original post clear.
Our window shelf is at 1050mm from the floor.
My questions are as follows.
With the smaller approx 850 wallk hung frame, can I/we
obtain the 420mm height to the top of the toilet pan including seat, plus or minus 5mm?
What will be the clearance under the toilet pan
Another question is, will the flush plates still be visible with the toilet cover lif still up.
Please see below  the link of this toilet set. I'm going for a set to avoid problems

This is the unit, only unit I can see that matches the max height criteria, link was also posted by another person here. This is one of the two brands that interest me, see my orginal post.
