A drip under the Wash Basin is easy to ignore until the cabinet smells and the floor stays damp. Most of the time you do not need a new unit. It is usually a loose nut or a worn washer or old sealant. You can fix it with basic tools and keep the same Wash Basin Sink in place.
First find where the water is coming from. Dry everything with a cloth and then run the tap. If water shows around the tap base the O ring or deck seal has failed. If you see damp along the rim the silicone between the basin and the counter has cracked. If there is a puddle under the trap the slip nuts are loose or the washer has gone hard. If the back of the cabinet is wet check the supply hose and the angle valve.
Turn off the isolation valves before you start. If there are no isolators turn off the main and open the tap to release pressure.
For a tap or mixer that drips most Wash Basin Sink mixers now use ceramic cartridges. Take the cap off and remove the handle. Pull the cartridge out and look at the small O rings. If they are flat replace them. Put three to four wraps of plumber tape on the thread and fit it back. Tighten it firm but not too tight because overtightening will crush the seal.
If water is seeping around the rim the old silicone needs to come out. Cut it away with a blade and clean the edge so it is dry. Run a new bead of sanitary silicone around the joint and smooth it with a wet finger. Leave it for twenty four hours to cure. This works for both countertop and wall hung Wash Basin types. If the basin rocks tighten the brackets first.
For leaks under the trap put a bucket underneath. Undo the slip nuts by hand and drop the trap down. Check the washers. If they are brittle throw them away and fit new ones. Clean out hair and soap then put it back and hand tighten plus a small extra turn. Test with water. If it still weeps the trap itself may be cracked and a new trap is cheap to fit.
Check the supply hoses as well. Feel along them for bulges. Tighten the nuts at the valve and at the tap tail. If a hose looks rusty or swollen replace it. Use tape on the thread only.
You only need to replace the whole basin if the ceramic is cracked through or the mounting points are broken or the tap body is corroded. Otherwise repair saves time and money.
If you do end up buying later look for a stain-free wash basin. The glaze is smoother so soap does not stick and you can wipe it clean. Rimless shapes and rounded corners help as well.
For basin price in Nepal it will depend on size and style. Wall hung basins are usually less than countertop bowls and mixers are sold separately. In Nepal Kohler Nepal stocks a range of Wash Basin and mixer options with local warranty. Ask for the cut out sheet before the countertop is made so you have the correct hole size and setback.
To stop future leaks wipe the rim after use so water does not sit on the silicone. Do not lean on the tap. Clean the aerator every few months so pressure does not build up. Turn the isolation valves on and off twice a year so they do not seize.
In terms of cost washers O rings and silicone are very little. A new trap or flexi hose is also low cost. A full Wash Basin Sink plus mixer is the bigger expense. If you are budgeting get two or three quotes and ask for basin price in Nepal for the exact size. For Kohler Nepal check lead time and whether the installer is approved.

When replacement is needed choose a stain-free wash basin check basin price in Nepal, and buy from a supplier with spares. Kohler Nepal is one option for both the basin and the mixer.
