Just lose the sink?

LOL. Nooooo. We need one in here for washing dirty stuff in ie dog things, my work paints etc.

The single sink in the kitchen will only be for prep and not used for dirty stuff.

That's the main use for it so really don't want to lose it.

Do you think a 400 sink would work?? Not even sure they exist. haha

This one could work, no? It's deeper than standard bowls apparantely and only 400mm wide..

as the stud wall is only 75mm deep, I won't be able to hide any pipes in there.

Only other alternative is to have the waste pipe for the sink running to the side and on the actual stud wall. Not the best solution - not sure of the drop it needs or if it can run straight along to the top of the floor and we can sort of box it in? LOL.

Yes you can get a single sink AND a washing machine into a 1100 space ... All you do is have a sink with the waste to one side, and fit it sideways. If however, the basin is in the way, as you suspect, just raise the surface so the bowl is above the washing machine. I suggest that unless you are super tall, look for a shallow basin. I did all this, but my basin is 200mm deep catering type sink so not ideal for the height of the surface.

The bath... if youre only using the 1600 bath to wash the dog and dont mind stepping over, or have small children, great. However, if you bathe the dog elsewhere, or prefer showering the dog in here, I would go for a walk-in shower because it will make the room look far bigger and the shower pace quite generous.

I just meant that you dont have to fully contain the sink bowl within the unit and dont have to put up with a tiny sink. Bath... I am completely the opposite, a house without a bath is hell to me!

Couldn't you have the sink where the washing machine is on your plan? If you had it orientated at right angles to the boiler, you would still get the benefit of the draining board and still get to the sink (which would now be facing into the kitchen) then you could put the waste out of the side wall.

Or even just put a sink in that corner with the draining board under the boiler.

I'm disagreeing with why it can't be done as planned. Both methods will work as waste pipe for a sink is only 32mm and will fit in your stud wall. Plus, I've never found concrete that won't come up with a Kango on it..........it may be hard work but it is do'able. I'd ask again, maybe the plumber won't be able to do it for himself, but one of the builders will surely?

MATH is correct. Nothing against following original plan. Waste pipe inside wall or bathroom side as there has to be waste almost on whole length of the wall (from basin trap) , I think Jonathan mentioned that solution above. Washing machine can be connected through stud as well. I am personally not big fan of stacking appliances and I would rather go for straight layout against long wall. Bin,corner unit with corner sink, WM, TD, but I have no idea what is under the boiler so may not work. Or if you prefer stacking start from WM and TD on the left and follow with base units.

I dint want to edit but one more thing, this radiator will be completely wasted money there. It will not heat the kitchen for sure and takes a lot of space.

Tani- yes to the above..............Maybe the builder wasn't too fussed about digging up the concrete, but then if he hasn't tried, how does he know how hard it is. Genuinely, i've never found anything i couldn't kango through. I managed to angle grind my way through granite earlier this year!! Tell him to eat some spinach before he starts. Ha ha. Besides which, I gather you're up for a challenge, go hire one ( it's about £15 a day round here ), and do it yourself, prove him wrong............it's really not difficult to get the hang of.

Also, agree with Oliver's kitchens and Bedrooms re the radiator. The kitchen will be warm any way due to the heating in that room, the bathroom sits behind the Utility and you therefore, in my opinion do not need one at all in that room.

Tani, the area is far away from any opening, that will be very unlikely circulating cold/hot air. Area itself will be warm due to WM/TD and boiler. You will not efficiently heat the kitchen , only waste the energy or you end up turning it off. You will probably gain a lot more if you put vertical radiator on the outside wall in the corridor behind the wall with sink ,if you are sure it will be must have item to do. Is the plumber a registered heating engineer? He should calculated how it will affect heating output and advise you.

I think i'd push for your original plan..............we have a motto here 'No such thing as can't', it may take longer, but it can be done. I had to go through the floor and the outside wall with my Utility for the washing machine and Tumble dryer, it's not easy but with the right equipment you get there eventually.

One thought on the rad - we are having an electric towel rail in our titchy utility, this will be used to give the utility some heating when the main downstairs heating is off, to help with drying laundry. Also will give a place to dry off wet coats, shoes etc. You might find it useful for these reasons?

However that’s obviously a “nice to have” so it may be the space or money could be better used in another way...

I’ve been stuck with a similar “it looked fine on paper” utility setup and yeah, plumbing routes can wreck the whole plan once someone actually looks at the concrete. In my last place we squeezed a slimline washer next to a small bowl sink, but it only worked because we used one of those compact sinks (like 400–450mm wide) and a washer that was a bit narrower than standard. You also need to account for the plumbing traps and hoses behind, because that steals more space than you think. Stacking is great but having a boiler right above is a pain, I’d be nervous about access/clearances for servicing.

If you’re in the Houston area and need someone who’ll actually give you a straight answer upfront on what fits and what’s code-friendly, I’ve had decent luck with Turbo Home Services. They were licensed/insured and could do same-day which helped when we were mid-reno chaos.
