August 21, 2004 - editor.  Pattaya, Thailand house construction and home building.  Prototype sample hose project.  Bathroom installation.  A pictorial history of the bathrooms being installed in the cool thai house prototype project.

One of the early problems with the bathroom is that the foundation base which is poured around the outside should be about 10 centimeters lower than the base of the house.  In this case it was poured about equal, to give extra strength.  This led to the necessity to reengineer a bit on the inside.  That led to the floors being only a few centimeters below the floor level of the house, where the normal difference is 10 centimeters.  As it turned out I like the small difference better, 3 centimeters is fine.  The only other misstep is the sink in the large bathroom is fitted in the cabinet a little too close to the wall and this necessitates bending over a bit when using it.

Central water heaters are a little new around here and it was a learning curve to get this one installed.  Normally houses use a small water heater for each shower, but in the end this turned out really nice.  The electrician did the copper pipe work, which is fitted within plastic PVC to carry the hot water.  The water heater is a 75 liter wall mount unit.

Another thing which you don't see all that often are shower enclosures.  These are gaining in popularity here.  This one is made with safety glass which is easier to clean than the acrylic types.

The small bathroom with 4" PVC for the toilet.
A septic being dug.  (22-Apr-04)
This shows the toilet septic for the small bathroom.  In all there are 4 septic tanks, 2 for water runoff and 2 for toilets.  There are 5 cement rings used for each one, the standard being 4.  Each ring is 1.2 meters in diameter.
The row of septics is dug behind the house.  There are two groups of pairs of septics.  From this side the sequence would be toilet, water runoff, water runoff, toilet. 
Here is a cement ring is being put in place in one of the septics.  (23-Apr-04)
The 4" PVC is run into the toilet septic.  The mallet is used to create the opening in the cement ring.  (31-May-04)
The PVC drainage from the small bathroom for the water runoff.  There are 3 exhaust pipes used for each bathroom.  One is for the bathtub (or shower stall), one is for the sink and one is for the outside drain.  The pipes are secured in place with a heavy cement.  (01-Jun-04)
The hot water is run through copper enclosed in PVC pipe.  (02-Jun-04)
This is the raw plumbing in the small bathroom, shown from the door opening counter clockwise.  This shot shows the outside drain pipe (3" standing) along with the 2" sink runoff.  The other PVC is the entry of hot and cold water.

The top shows the heavy duty bathtub drain assembly which was purchased separately for about 1700 Baht.  On lower portion shows the default drain assembly which comes with the bathtub.  You wouldn't want to use this plastic type.  (23-Jun-04)
The plumber finishing off the shower enclosure.
This is a critical piece of plumbing which is used under the bathtub.  Without it, for one thing, foul smells can flow in through the bathtub from the water septic.  (24-Jun-04)
Heavy duty drainage assembly being attached to the bathtub.  Note; this is a heavy duty acrylic bathtub.
Bathtub in the process of being framed.  The bathtub is being sized here.  After this two more rows of supporting bricks were added, for a total of 4 supporting rows.  (25-Jun-04)
