I suggest you follow the step-by-step guide for creating storage cabinets under the bathroom sink. Take proper measurements - Measure the available available space in height, width and height. Cut Plywood to size - With a circular saw and framing square, cut all the required pieces out. You can use a sliding compound saw as an alternative. Attach the base and sides - Start assembling the sink cabinets by placing the bottom piece of plywood sheet on a flat surface. Attach the back and top boards - Place the plywood sheet for the top part of the cabinet and attach wood screws to connect it to both the sides. Turn the back faces of the cabinet upwards. Keep the back piece over the structure and fix it into place with wood screws. Attach shelves - Place the cabinet in an upright position to install the shelves. Slide a shelf into the structure so it is flush against the back. Attach door - Keep both hinges of the door on the same side of the plywood sheet. Drill them using wood screws into place. Now keep the door over the cabinet structure, extend the hinges to one of the side panels and fix them to make them secure. Fix a hasp closure on the other side of the door, placing it in the center of the hinges.

Thx for the input. I had not put any thought in it....Was just looking for comments if it's a good or bad idea. I guess it's a bad idea :)

Some pics of the pieces would be good.30” tall is a bit low for a vanity so you will need to use vessel sinks for sure.

Hello Paridhi, You should use Walnut in the base cabinets and white on the wall cabinets with the top ledge being in walnut. Refer an image attached.. Please do not use black and white combination, especially glossy black with glossy white. Even if you have already purchased the black laminates I would recommend not to use it.. Besides this there are few things you should take care of.. 1-The cabinets and the slab width are same. Slab should be 1-2 inches more than the cabinets. Please fix this otherwise the furniture will get spoilt very soon. 2-The bottom end of the cabinets should leave 3inches of space..right now it is 1 inches..It must be raised. 3-There are no drawers in the plan, it is quite inconvenient to store cutlery, vessels within doors. 4-There is no provision for a chimney here. Hope you have thought well about it. 5-The rafters are made in POP whereas the inspiration one are made in wood. It requires a very skilled worker to get a close walnut finish. Please get a sample done before you go for the walnut polish. Thanks Nitin CORNERSTONE DESIGNS Bangalore.
