Especially advisable for the drainpipe leaving the washing maschine room. As clogging starts centimeters after the used water leaves the washing maschine. Reason is predominantly the "unstoppable" overdosage of washing powder. Having a bigger pipe helps to avoid the clogging or recurrent pipe cleaning.

I have had 2 inch pipes draining from both the shower room, and wash house, without a problem for the past 3 years.

Should I get the builders in to rip up both floors (tiled), and replace them with 3 inch?

No, the recommendation to use bigger pipes is mostly directed to builders in the early phase of planning.
But You correctly describe the potential costs ("to rip up both floors (tiled)") of a late correction of a suboptimal decision. :-"

I gave repeated instructions for no bends in the pipes, as it causes blockages..am with you on that, but many things have gone this way...there seems no reason for the bends either....will voice it again....are you a drainlayer by chance

Diameter depends on the length of the run, and the grade (Q=A.V).

Q = flow, A = pipe area, V = velocity of flow.

If its a long run on a shallow grade a larger size is better.

If its a short run with a reasonable grade then a smaller size - 2 inch - should do over 2-3 metres.

Increasing pipe grade increases velocity.

Long pipe runs and bends contribute to energy loss, which reduce velocity (V).

Slow flows allow sediment to build up.

Voiced my concerns yet again, well after my plumbing plan was never followed, after my solar hot water system has been scraped, about the bends again, and blockages...'what blockage them..i no use toilet paper nor do you, so what block them...ahh what about farang guests we cant expect them to use water gun..i will tell them to throw tissue in plastic bag..ooooohh yuck..you cant do that.. .what I tell them to poo before visit...it my house I will tell them use plastic bag like they do at home hub and throw in rubishs......cant win john......we dont use loo paper and dont have washing machine

Alternatively, you prescriptively describe what may be total over specification.

Why not 4 inch, or 5 inch? Is 3 inch not potentially suboptimal?

To calculate what is optimal for a given situation read and understand the last post by ronan01.
The specialty with pipes from washing maschines is pretty much known among those having such maschines and do not use only liquid washing lotions.

In Aus as soon as you go under ground, meaning under slabs or buried in trenches all pipes are 4". I also used 3" once underground didn't bother with 4" to save a bit but always 2 X 45 deg bends as opposed to 90 deg bends.

No, not a drainlayer, makka! Just bored of having to unblock badly laid drains that could have been made twice as well just as easily and cheaply with just a little thought.

I actually went to uni to be an architect but dropped out as I couldn't face the 7
years of study, but I can still (vaguely)
remember some of the basics needed
for the first steps of surveying, double
syphonic toilets, and other exciting
things that I've never thought about for
nearly 40 years!

The reason its a problem with farang
houses but not Thais is the old 'worst
of both worlds' issue. Thais usually
have the soakaways and drains near
the house so its not an issue for them in the village but farangs want them further away so you have a longer run of pipe, sharp corners and bends, pipe sag or not enough drop, etc. Their system works, but only if its applied under the same conditions. Once you change the goalposts that's when the problems happen.

Hadn't noticed some of the last posts, so I'm just reinforcing what they said.

I expect all will be fine, but I really would insist about changing the 90 degree bends to 2 x 45's. You haven't got much of a drop (?) so even without the toilet paper something big, nasty, sticky and smelly could all too easily get stuck on a sharp corner, particularly as some of the internal casting on the 90 corners can 'catch' something going by. In my last house we never had a problem except with one particular person when there was always a 50% chance of a blockage - he was a Thai, coincidentally, but if you want to be tactful try explaing 'some farang big tut, not same Thai, so big kee'! You're talking a couple of hundred baht to change them as long aa you do it now.

I had been considering building a new house. The place I wanted the new house is off the electric grid so that meant a total solar electric power supply. That would have been doable but expensive. My wife then started talking about expanding and remodeling our existing house. We ended up adding on and remodeling the existing house. I saved a lot of money and she got exactly what she wanted. She always asked my opinion then did exactly what and how she wanted it done. I soon gave up saying anything at all and just let her carry on. It actually came out pretty good but cost me about double what I had planned on. Still much cheaper than a new house. She is happy and that means that she makes me happy. Actually the added on space is wasted but that's what she wanted. I have my air conditioned computer room with the computer and lights solar powered so I am happy.

I'm sure at the end of the day all will be honky-dory. Probably be able to have a few laughs while slurping a few Steinies and reflecting on the trials and tribulations!

yes I am sure we will laugh at this one..drawing the kitchen layout on the wall so she knew where everything went

due to costs we decided to use floor tiles as sink top and cabinet tops...i wanted green marble but the missus just used the same floor tiles...due to being a heavy traffic area we cut the corners off the tops

That works OK
