I suppose the wall and floor tiles are done up by HDB already.
So things you need to do are:
1. Lighting ( i think the powerpoint are there. but need to buy 1 and install? ) , a good one, cost less than $100
2. cabinet with table top ( this is the expensive part ) contractor measure by Square feet. with cemeted base.
for me, i paid about 2-3K for my cabinet with granite table top. i had 5 doors at the top, 5 doors at the bottom, with 1 door section for drawers. materials all inclusive.
3. wash basin with tap ( there's alot alot alot of designs. have to go showroom and choose ), less than $200 can get not bad one already.
4. Hanging laundry? not sure if you need this. i bought those aluminium type, with 6 aluminium poles, around $80-$100
5. cooker hood and hob.
everyone expectation for a kitchen would be diff. for me, simple is good. coz i seldom cook.
can take a look at my kitchen at the other thread.
