Buying Guide: You must know to spruce up your bathrooms

Core material

The core material used in the production of bathroom sinks is usually porcelain or vitreous china and ceramics. Vitreous china is just another name for good old porcelain. The sinks made of porcelain are usually more glossy, stain-resistant, and relatively easy to clean. These are used as core material to make the sinks more durable and long-lasting.

Faucet compatibility

Not all sinks come with faucets. You will need to place the faucet on the wall or on the countertop. Before doing that, you need to make sure of the sink’s faucet compatibility before purchasing it. You need to be careful while choosing the sink’s shape and size, as it is quite crucial for setting up your faucet.

Size and shape

At present, sinks are available in different shapes and sizes. Well, there is not a standard for undermount bathroom sink sizes , so you need to check the dimensions of the sink before purchasing. Most bathroom sinks round bowls are 15-20 inches in diameter, rectangular ones have a width of 16-24 inches, and 16-23 inches from front to back. The depth of a typical basin is around 5-8 inches. The shapes are a matter of one’s personal choice unless you’re thinking of replacing your old sink.        

Easy cleaning and stain resistance

Sinks constructed with vitreous china are comparatively easier to clean. You can use a sponge or a soft piece of cloth and mild washing soap to clean your sink.
