1. Kohler is cheap, almost 1/2 price. But fakes are common.
2. Grohe can be about 20% cheaper, but also beware of fakes.
3. Copycat designer furniture/fixtures are abundant.
4. China designs are a lot more "modern" than what most local shops carry, especially light fixtures.
5. Toilets are a steal from China. So many brands, designs, colours. But official Taobao logistics don't transport porcelain.

Yes, I bought recently or last few months...
Lights, bathroom stuffs including bidet, tap, hose, sink, mirror, etc. Just need to ask the seller or the logistics there to pack accordingly and add protection if required with extra charges.
Last 2 weeks there are big jump on the shipping fees, so you need to pay more for the shipping fees now.

If you go survey at Puchong lighting shop, you will find most of them selling china products also with markup price. So you may go and compare before buying from TB or Shops.
But take note also the risk of buying lights/electric appliances directly from TB....For downlights, I bought Philips online from Shoppee because of SIRIM cert.
For fancy lights, I bought from TB. Just ask the seller whether support Malaysia plug/wiring/voltage, i.e, 3 pin UK plug, 240V, 50Hz power supply.
