LOL, I was surprised too. 

Wooden Doors

Went in search of wooden doors.
Visited 5 shops.
Below are a few points I've got.
I may be wrong, feel free to correct me.

Generally solid wooden doors are graded in 3 main categories.
A, B and C.

A- Very nice and relatively even wood grain / lines.
Can go for light colour varnish / shellec - to show off the nice grain / natural pattern

B- Medium quality wood grain / lines
Either dark colour shellec or solid paint - to hide the unevenness

C- Lower quality range usually mixed wood.
Solid paint only is recommended - hide everything

Wood for the mid to high range can be Nyatoh, Meranti, Merpauh..

Standard size is 33 6/8" X 83". The width is the same but the length is usuallu needed to be cut to suit your door frame.

The cost:-
The price I've encountered is verrryyy varied. 
Generally
Door + Installation + Painting + Lock

I concentrated on Nyatoh B and Merpauh

Door - RM 250 to 380 to 430 / pc
Install - RM120 to 150 to 200
Paint - RM100 to 200
Lock - RM20 - RM 200 or more

Some even charge transport seperately.

For narrower doors, it is not so easy to find so quite pricey for wooden doors.

Another option is Plywood doors.
It is not solid but cheap and has very modern pattern.
1 plywood door RM 350-380 include instalattion.

Actually if your frame is still OK can still use back. save $$$.

For Wood frame, is calculate by foot run for non standard size. Standard 3x7 door frame is cheaper. But is still depend on wood type.

Mine are all wood, installation done by wet work contractor, painting by the door painter. If I am not wrong, it add up to about RM 300 - 350 per door frame, this exclude the skirting. My main door is 5x8 and is much expensive too.

I use aluminium frame, forget the price already, 
Aluminium frame with nice looking door, door will look cheap, - depends on the individual. 
Got money and willing to spend, everything will look expensive, 

wow.. very big door. the same size apply for bed room door also? where do go get those door with the frame?
