I'm considering paying for an addition to an existing old Thai farm house. This would be a gift. I want nothing to do with owning a house.

All I want is to add a real Thai style bathroom with water heater, shower, sink and toilet all in one, and also a small bedroom, maybe 3 meters by 4 meters at most. The house has electricity and a "septic tank."

Can anyone give me a guesstimate as to what such things might cost in very rural Surin Province. I mean in the province but 2 hours North of Surin in the middle of nowhere in a village of about 100 homes.

Any experienced guesses would be Greatly Appreciated.

a real Thai style bathroom...

Are you sure you want it to be real Thai style?

Here is a photo of the real Thai toilet...

Also check the water pressure - I made the mistake of installing water heater before where pressure varies from low to not at all. Wasted my money as never could be used.

thats not a thai toilet,thats a " thai bomb site"

This may not be helpful, but I have just finished a complete rebuild of a house in a village north of Korat. It now has 4 bedrooms, a european style toilet with water heater type shower. A combination of wooden shutters and plastic windows / sliding door - floor tiling and wall tiling in toilet / shower room.

I used local and specialist labour and the all in cost, inclusive of new appliances (fridge, washing machine, etc) was one million baht.

OK, I'm talking about an older Thai style home. Yes it has good water pressure.

I just want to put an addition on it that has a bathroom with shower, sink and toilet (yes, American style toilet 5555 ) and also a modest sized bedroom. It's not going to be a million baht 555.

I would appreciate some educated guesses as to what that would cost.

As it is an addition, can the two rooms be lean-to style? This would keep costs down along with cementitious panel roof covering.

(Whcih may be a bit noisy under a lean-to, but hey I live happily under one.

You've got about 16-17sqm.

One can build in a non city area like yours for 7-8,000/sqm for a pretty well finished but non hi-so bungalow including a wall and heavy roof tiling and all services.

You could well be considerably cheaper, no fuse box etc etc.

For simple but really quite respectable construction and modest materials and roof like I say I'd say ballpark 100k but you could be more frugal 50 or 60 or of course it would be easy to go well over.

In fact I think mum in law built a free standing little place about 5+ metres square at one of her houses as a crash pad or to rent out for 30,000 including bathroom......but it is pretty basic. Could even have been less.

On reflection for basic Thai village style....if that's what you want.....would be the lower end of what I mentioned.

Ever heard of water pumps?

Hi Neversure,

I have just completed something similar to what your talking about....and I spent with labour about 70K baht....but it's more western style than Thai.

Laour costs were 40k baht....Pm me if you want some photos to give you an idea.

That's about it.

Fancyish......100k-sky's the limit.

Nothing special but moderately good finish farang standards 60-120k

Thai village standard 30-50k

We concur??

But easy to find out if somebody had "explosive diarrhea" before.-

A “guesstimate” would be from 100,000 baht and up, depending on decoration and hardware – could be 200,000 with a small bedroom included.

I’ve spent almost 200,000 for a bathroom and a fairly big kitchen (Thai style, nothing fancy) some years ago, but including some 35,000 for water drill, pump, filters etc.

I am building a new 2 bedroom 50 km west of Korat. I have to run my own electric powerline (200,000 baht), but to build the house by itself will cost about 550,000 baht (incl labor)....it's about 90 square meters....bedrooms are 4 x 4 and 3 x 4....one master bath (2 x 3) and a second bath (2 x 3)....3 x 3 kitchen....4 x 8 living room / dining area.

Depending on what amenities and materials you use, the cost for your bedroom complete could be 30,000 to 50,000 based on the material build list for my home. If you pay more than 100,000 bath....then you or your builder have expensive taste....so whatever blows your hair back (if you still have hair). For my build, I estimate approximately 5000 - 6000 bath / square meter. These are my facts and figures for my house only....I have done all of my own design including the steel design for the roof (and I cross my fingers that the thing doesn't collaspe, but I always over engineer most everything). Back in the states I ran my own construction company. When you calculate all of the different materials that can be used in Thailand to build a home....your range for build can be all over the board. If this is helpful...great.....and good luck

We had a new bore put in 4,000 baht. That included the PVC liner and the bottom pipe from the jet down. A pump with fittings 5,000 baht.

Edit: bore was approx 27 metres deep

I agree with this guy....too funny

I had a western bath put on the back of the outlaws. 2 x 3 meters, hot water, pump tile, sink flush toilet, all cost 30000. This was near surin, last year.

If there is builders within the "family" no need to spend more than 30.000.

Also check the water pressure - I made the mistake of installing water heater before where pressure varies from low to not at all. Wasted my money as never could be used.

No probs can use heater if you install 500 ltr tank and small pressure pump I had to do that,works fine now already for 2 years )

If water pressure is low they now sell one water heater with a pump build-in to increase the pressure. Just ask the sales person. Also inside the unit it has a copper (not plastic) heater element piece. The unit is more expensive but it is superior quality. The unit is made outside Thailand, it's actually made in EU.

so whatever blows your hair back (if you still have hair).

I still have all of my hair. Do I get a discount?

Thanks everyone for the answers. This is a gift, will be real basic because the house is an older wooden Thai home, so I'm going to try to hit the low end - maybe 40k - 50k in the middle of what people have said. If I miss, oh well...

At least I have some ideas and I really appreciate it.

Since you live in Issan it will be cheaper than if you lived in Pattaya or Bangkok. I would guess somewhere around 50,000 baht but could go higher depending on how lavish you want the bathroom equipment to be. I live outside of Korat and had a double carport, covered patio and enclose the Thai kitchen I have outside and the cost was 50,000 baht. You need to buy all the fixtures and building materials. if you don't the contractor will add on his cut. Also, get a couple bids on the labor cost and if possible go see some of the contractors work. Don't always go with the cheapest bid as the work might be shabby. Good luck.
