Which Vastu Defects Are Worth Fixing Before You Buy a Flat (And Which Are Cosmetic)

Short answer: the split is decided by how much of a bad placement comes back without construction. In the table our check runs on, five room types are anchored to plumbing, fire or structure — the toilet, the kitchen, the staircase, the main entrance and the garage — and a bad placement of those recovers only 45–50% of what it costs. Every other room recovers about 85%. So a master bedroom, pooja room or living room in the wrong zone is close to cosmetic: nearly all of it comes back by re-designating rooms and changing use. A kitchen, toilet or main door in the wrong zone does not. Those three are the before-you-sign checks.

The number nobody else publishes

Every "major vs minor Vastu defect" page in this genre sorts faults qualitatively — serious, moderate, easily remedied — and several of them (VastuPlus, VastuAgent) go further and promise that every defect is fixable without demolition. That is the part worth disagreeing with, and we can disagree with a number rather than an opinion.

Our scoring holds two figures per room. The first is a weight: how much that room moves the overall verdict at all. The second is a recovery fraction: how much of a bad placement's deficit non-structural remedies actually recover. Multiply them and you get the figure a buyer actually needs, which is not what a defect costs — it is what you are still carrying after you have done everything you can do without a contractor.

The ranked table

Each row takes the worst cell on that room's row in the placement table, for a 2BHK room set (entrance, kitchen, master bedroom, second bedroom, living room, toilet, pooja). "Costs" is points off the overall score; "recovers" is what non-structural remedies bring back; "residue" is what you are stuck with.

Room, at its worst zone	Score	Costs	Recovers	Residue
Kitchen in the north-east	15 (avoid)	16.4	7.4	9.0
Main door in the south-west	25 (avoid)	16.3	8.1	8.1
Toilet in the north-east	15 (avoid)	12.3	5.5	6.8
Master bedroom in the north-east	25 (avoid)	11.7	10.0	1.8
Pooja room in the south-west	25 (avoid)	8.1	6.9	1.2
Living room in the south-west	45 (avoid)	5.3	4.5	0.8
Second bedroom in the south-east	45 (avoid)	4.6	3.9	0.7

Read the last column and the genre's advice reorders itself.

There is a cliff after the third row. The top three defects leave behind 6.8 to 9.0 points each. Everything below them leaves 1.8 or less — a four-fold gap with nothing in between. Put all four of the lower rooms in their worst possible zone at once and the permanent damage adds up to about 4.5 points, half of what a north-east kitchen alone leaves behind.

And the master bedroom is the row that changes character. A master bedroom in the north-east scores 25, the same as a south-west main door, and it is squarely in the avoid band. Gross, it costs 11.7 points — nearly as much as a north-east kitchen's 16.4. But 10 of those 11.7 come back, because a bedroom is not plumbed or load-bearing. It is a room you can re-designate. Swap it with the south-west bedroom and the defect is gone, for the price of moving furniture. The genre puts this defect near the top of its warning lists; on the residue column it is fifth-of-seven and barely above the pooja room.

Why the three anchored rooms are different

Nothing mystical: they are attached to the building. A kitchen is a gas line, a chimney and a drain. A toilet is a soil stack shared with the flats above and below you. A main door is a hole in a structural wall opening onto a common corridor you do not own. In a flat, none of those three is yours to move — which is exactly why the model gives them a recovery fraction of 0.45 to 0.5 instead of 0.85, and exactly why they belong on a pre-purchase checklist rather than a post-purchase one.

The worst single cell in the whole table is a toilet in the centre of the plan, at 10. If a plan you are considering puts the toilet in the Brahmasthan, that is the one to look at hardest — you can see where the centre of your plan falls with the Vastu grid.

What this does not mean

Three honest limits, because a ranked table invites over-reading.

• A defect that recovers 85% is not a defect that disappears. It means the remedy is re-designation and use, not construction. You still have to actually do it.
• Our model applies no recovery at all above a score of 70. A room in the good band (70–89) gets no remedy credit in the arithmetic, on the grounds that it does not need one. So the table above is about avoid-band faults, not about squeezing points out of a decent layout.
• The best reachable score is capped at 96, not 100. No amount of remedy work makes a compromised plan a perfect one, and any tool that tells you otherwise is selling remedies.

We also grade the zone a room falls in, not the wall it shares, the slope of the plot, what sits above or below it, or the road level. Those need eyes on the property.

The three checks before you sign

1. Where is the kitchen? South-east is 100 (ideal), north-west 80 (good). North-east is 15 and it is the most expensive permanent fault in the table.
2. Which way does the main door face? North-east 100, north 95, east 90, north-west 75, west 70 — all good or better. South-west is 25, and it is the lowest cell in the entrance row.
3. Where are the toilets? North-west 90 (ideal) and west 85 are the good answers. North-east is 15, centre is 10. In a 3BHK the second toilet counts as much as the first.

Everything else — the bedrooms, the pooja room, the living room — you can very largely sort out after you have the keys.

You do not have to do this arithmetic by hand. Run a free Vastu check on your floor plan: upload the plan, confirm which way north points and the room labels, and you will see which zone every room falls in and a score. If you are working through a purchase room by room, the 2BHK and 3BHK checklist covers the same ground in walkthrough order.
