The short answer
Sometimes, yes. The old tiles must be firmly fixed, and the new layer must fit the door, drain and fittings. A leak or weak base needs its own repair first. Do not choose tile-on-tile only because it means less breaking.
1. Know what you are keeping
Tile-on-tile means fixing new tiles over the old ones with a suitable adhesive. Adhesive is the material that holds the tiles in place. The old layer stays under the new one.
This can cut some removal work, noise and waste. It does not mean no dust or no disruption. Cleaning, repairs, cutting and fitting may still be needed. Ask what the full job includes.
For an occupied flat in Kudasan or a sector home, less breaking may sound helpful. But the room must pass the checks below. The address alone cannot tell you if the old base is sound.

2. Ask the tiler to check the old layer
Look for loose, raised or cracked tiles. Ask the tiler to check how well the old tiles hold to the surface below. A hollow sound can be a warning. A tap check is not proof that every hidden part is good.
Ask the team to mark any weak spots and explain the repair. If damage is spread across the room, covering it may leave the new tiles resting on a weak layer. Get the cause checked before choosing the work.
Wall tiles need a separate check. A new layer adds weight. Ask whether the wall and old fixing can carry it. A product suitable for a floor is not automatically right for a wall.

3. Deal with leaks before a new look
Tell the team about damp walls, water marks below the room, leaks tried before and water that stays on the floor. These are clues, not a diagnosis from a photo.
Ask a plumber or waterproofing specialist what needs checking. Waterproofing is the system that keeps water from reaching parts of the building that should stay dry. New tiles alone do not prove that system is sound.
ARDEX warns against covering a wet area when the old waterproofing is in doubt. Ask for a clear repair and test plan. Do not agree to hide an active leak under new tiles or grout.

4. Check the door, drain and finished height
The new tile and its fixing layer take up space. Ask the tiler to show the planned finished height at the doorway. Check the door swing, the step into the room and any nearby fittings before ordering.
Ask how water will still reach the drain. A fall means a gentle slope towards it. Covering a floor should not leave the drain too low or high, block its cover, or create places where water sits.
Do not settle this by trimming the door first. Let the team check the whole floor and drain plan. If the drain or hidden pipes need changing, include that work before comparing prices.

5. Name the tiles and fixing system
Ask for the tile type, size, adhesive product and any primer in writing. Primer is a coat used to help the next material bond. The maker must allow the chosen products on the actual old surface, in that room.
Do not use one mixing, drying or waiting time for every product. Follow the current instructions for the whole system. Agree when the bathroom can be used again.
When comparing samples in Gandhinagar or Gota, take the site notes with you. Shyam Granite & Tiles lists bathroom choices at its Gota showroom. This is a shopping example, not a stock or price check. Confirm availability and suitability yourself.

6. Compare two complete work lists
Ask for a cover-over option only if the checks support it. Ask for a removal-and-repair option too. Include preparation, leak work, drain changes, fittings, waste, tests and taxes where needed.
Example: a dry bathroom with firmly fixed tiles may suit a surface update. Another bathroom has leaks and loose tiles near its drain. The second needs the cause and base dealt with first. These are planning examples, not reports of local jobs.
