If you are planning a 4-room HDB renovation in Tampines and want actual numbers you can plan a budget around — not range estimates from a dated forum post — this guide covers everything in one place. Whether you just collected keys for a new BTO in Tampines Nova, bought a BTO resale unit along Tampines Street 83, or moved into an older resale flat in Streets 11, 22, or 33, the packages, pricing, and permitted methods change depending on your flat type and what condition the existing finishes are in.
A 4-room flat is the most common HDB type in Tampines, spanning roughly 90–95 sqm of floor area. That extra space compared to a 3-room means slightly larger kitchens, more bedroom flooring, and higher bare unit costs — but the wet area packages (kitchen and toilets) remain very close in pricing because bathroom and kitchen sizes are standardised across most HDB flat types.
All pricing in this guide is taken directly from verified RCS 4-Room BTO collection page and RCS 4-Room Resale collection page, confirmed against live product listings as of April 2026.
4-Room BTO Package Pricing — All 14 Packages Verified
For a 4-room BTO flat in Tampines, renovation costs range from S$5,590 for kitchen cabinets only to S$19,390 for a full bare unit premium tiling package. RCS breaks 4-room BTO renovation into modular packages so you pay only for the scope you actually need:
Pricing note: All 14 BTO figures are verified against the live RCS 4-Room BTO collection page as of April 2026.
Understanding Every BTO Package Type
Move-In Package — S$7,690 to S$8,390
Designed for new BTO owners who want the flat liveable from Day 1 without committing to a full renovation upfront. It covers essential electrical works, basic lighting, painting, and minor fittings — enough to move in comfortably while you plan the bigger works later.
Best for: Couples collecting Tampines BTO keys who want to move in quickly. Plan the kitchen and toilets as Phase 2 once you have lived in the flat and know how you actually use the space.
Kitchen Cabinet Only — S$5,590 to S$6,190
Cabinet fabrication and installation only — no tiling, no plumbing rework. You get 10ft of bottom cabinets, 10ft of top cabinets, a quartz countertop, soft-close hinges, and a stainless steel dish rack. Your existing kitchen tiles, plumbing, and electrical connections stay as they are.
Best for: BTO owners whose kitchen tiles and plumbing are in good condition but want a properly designed cabinet setup instead of living with the builder's default.
2 Toilets BTO Package — S$9,990 to S$10,390
A full renovation of both bathrooms — dismantling existing fixtures, tile overlay on floor and walls, new WC, bidet, basin with mixer tap, rainshower column, and a 15L storage water heater. Completed in 5–6 working days.
Best for: BTO owners who want to transform both toilets now while keeping the kitchen and living areas for later. The toilet is the one space every household member uses multiple times daily — renovating it first makes an immediate difference.
Kitchen Full Package — S$11,290 to S$11,790
The complete kitchen renovation: tile overlay on floor and walls, 10ft bottom and top cabinets, quartz countertop, sink and tap, hood point electrical connection, and all finishing works.
Best for: BTO owners who cook daily and want a kitchen that is actually designed for their workflow — proper cabinet layout, enough counter space, and electrical connections that can handle a hood, oven, and microwave simultaneously.
Kitchen + 2 Toilets Combo — S$18,390 to S$18,990
This is the most popular bundle for 4-room BTO owners in Tampines. It combines the full kitchen renovation and both toilet renovations into a single project — with a built-in discount versus buying separately.
The bundle savings are real: Kitchen Standard (S$11,290) + 2 Toilets Standard (S$9,990) = S$21,280 separately. The combo at S$18,390 saves you S$2,890 — a 13.6% discount — while consolidating everything under one project manager, one timeline, and one warranty.
Bare Unit Package — S$16,390 to S$19,390
Covers the living room, dining area, and all bedrooms — the dry areas that kitchen and toilet packages do not touch. Full floor tiling (or vinyl) across the entire unit plus skirting.
Tiles vs vinyl for a 4-room flat: A 4-room flat has approximately 90–95 sqm of floor area, making the cost difference between tiles and vinyl approximately S$2,000–S$2,500 across the full unit. Tiles last 15–20 years, stay cool in Singapore's climate, and require virtually no maintenance. Vinyl installs faster and suits homeowners who might change flooring within 8–12 years. For a flat you plan to stay in long-term, tiles are the stronger investment.
4-Room Resale Package Pricing — All 16 Packages Verified
This is where the data gets significantly more detailed. The 4-Room Resale collection page lists 16 distinct packages covering every combination of scope, method, and tier. For resale flats, both overlay and hacking options are available for each package type.
Kitchen & Cabinet Resale Packages
2 Toilets Resale Packages
Note: 2 Toilets Resale Premium (Overlay) at S$11,990 and 2 Toilets Resale Standard (Hacking) at S$11,990 are the same price. The scope is different — overlay gives you upgraded fixtures on existing infrastructure, while hacking gives you standard fixtures on a completely rebuilt foundation with new waterproofing and piping. For flats older than 15 years, the hacking option at the same price is almost always the better long-term value.
Kitchen + 2 Toilets Resale Combo Packages
Bundle savings for resale: Kitchen Resale Standard Hacking (S$14,390) + 2 Toilets Resale Standard Hacking (S$11,990) = S$26,380 separately. The combo at S$24,990 saves you S$1,390. Smaller discount than BTO bundles, but you also gain single project coordination, one permit application, and one unified warranty.

How to Decide What You Need
New BTO — Tampines Nova, Tampines Bliss (Keys from 2026)
Your flat is within the 3-year TOP restriction. Hacking is not permitted. Everything is new — the waterproofing is intact, the piping is fresh, and the concrete base is sound. Choose based on priority:
-
Tight budget, move in first: Move-In Package at S$7,690 — makes the flat liveable now; renovate kitchen and toilets in Phase 2
-
Kitchen + toilets only: Kitchen + 2 Toilets Combo at S$18,390 — the most popular choice; transforms every wet area while keeping the living room and bedrooms as-is
-
Full transformation: Combo + Bare Unit — combines the kitchen + toilets bundle with full living area tiling for a complete floor-to-ceiling renovation of the entire 90–95 sqm flat
Browse all BTO options on the 4-Room BTO Packages page.
BTO Resale — Tampines GreenBloom, GreenVerge, Earlier Batches
If your block's TOP date was more than 3 years ago, you can choose overlay or hacking. Start with the tap test on every tiled surface. If tiles are solid and the infrastructure looks healthy, overlay packages are the practical route. If you find hollow tiles, moisture staining, or corroded piping, hacking is the safer long-term decision.
The BTO resale tier sits between BTO and full resale pricing — reflecting infrastructure that is no longer factory fresh but is not yet at end-of-life. Browse options on the 4-Room BTO Resale Packages page.
Older Resale — Streets 11, 22, 32, 33 (Built 1980s–1990s)
For flats this old, partial renovation is rarely worth it. You end up with a new kitchen next to 35-year-old bedroom tiles, or new toilets connected to original piping that corrodes within 18 months.
Two whole-house options are available:
-
Hacking at S$37,490 — Full demolition and rebuild with new tiles throughout. Best for flats where the existing infrastructure is beyond useful life.
-
Vinyl at S$30,490 — Same wet area rebuild but with vinyl flooring instead of tiles in dry areas. Saves S$7,000 and suits homeowners who may change flooring again in 8–12 years.

HDB Rules That Affect Your 4-Room Renovation
The 3-Year Tile Restriction
HDB does not allow homeowners to remove or replace floor and wall tiles in wet areas within 3 years of the block's TOP date — not your key collection date. All BTO owners in Tampines Nova and Tampines Bliss are restricted to overlay for kitchen and toilet tiling. Dry area flooring (living room, bedrooms) is not subject to this restriction.
Permits for Hacking Works
Any work involving tile removal, floor demolition, or structural modification requires an HDB renovation permit. Processing takes 1–3 weeks; complex applications may take up to 4 weeks. Overlay does not require a permit. For all RCS hacking packages, the permit application is handled by RCS — you sign the acknowledgement form, and they manage submission and approval.
Hacking Hours
Hacking is only allowed on weekdays from 9:00 AM to 5:00 PM. No hacking on Sundays, Public Holidays, or eves of major holidays.
All renovation rules are published on the HDB official renovation portal. Verify your contractor on the HDB Directory of Renovation Contractors before signing anything.
How Long Does 4-Room Renovation Take?
For overlay-only BTO projects, you can often continue living in the flat during the work. A 4-room flat has enough room separation that your contractor can sequence the work — kitchen first, then common toilet, then master bathroom — so you always have at least one functioning wet area.
For whole-house resale hacking, the flat is completely uninhabitable for the first 4–5 weeks. Most Tampines homeowners either stay with family or book short-stay accommodation during this phase.
The Smart Way to Phase Your BTO Renovation
Not every 4-room BTO owner can — or should — commit S$35,000+ on Day 1. Phased renovation lets you spread cost over time without compromising quality at any stage.
Phase 1 (Move-in week): Move-In Package at S$7,690. Covers essentials — lighting, painting, basic electrical. You move in comfortably within a week.
Phase 2 (3–6 months later): Kitchen + 2 Toilets Combo at S$18,390. After living in the flat for a few months, you understand how you actually use the space — and you make smarter design decisions for the wet areas.
Phase 3 (12–18 months later): Bare Unit Package at S$18,490 (tiles). Living area and bedroom tiling completes the transformation.
Total phased cost: S$7,690 + S$18,390 + S$18,490 = S$44,570 spread over 12–18 months. You pay slightly more than doing everything at once, but you never need to find the full budget upfront — and each phase is done by the same contractor with the same warranty standard.

Frequently Asked Questions
How much does 4-room HDB renovation cost in Tampines in 2026?
From S$5,590 for kitchen cabinets only to S$37,490 for a full whole-house resale hacking rebuild. The most popular BTO option — kitchen + 2 toilets combo — costs S$18,390 (Standard) to S$18,990 (Premium). Browse BTO options on the 4-Room BTO Packages page and resale options on the 4-Room Resale Packages page.
Can I hack my new 4-room BTO flat in Tampines?
Not within the first 3 years from the block's TOP date. Overlay is the only permitted method for wet area tiling during this restriction period. Dry areas (living room, bedrooms) are not subject to this restriction.
Should I renovate everything at once or in phases?
If you can comfortably afford S$18,390–S$37,490 upfront, doing everything in one project is more efficient — single disruption period, coordinated timeline, bundle savings. If budget is tight, phased renovation starting with the move-in package at S$7,690 lets you spread cost over 12–18 months.
Is 2 Toilets Resale Premium Overlay really the same price as Standard Hacking?
Yes — both are S$11,990. The difference is scope. Overlay gives you upgraded fixtures on existing infrastructure. Hacking gives you standard fixtures on a completely rebuilt foundation — new waterproofing, new piping, new doors. For flats older than 15 years, hacking at the same price is almost always the better long-term value because you are investing in the foundation rather than the surface.
My 4-room Tampines resale flat is 30 years old. Can I just do the kitchen and toilets?
You can — the Kitchen + 2 Toilets Resale Standard (Hacking) at S$24,990 covers all wet areas with a ground-up rebuild. But for a 30-year-old flat, the living room flooring, bedroom tiles, and general electrical are also at end-of-life. The whole-house package at S$37,490 addresses everything in one project so you do not need to revisit the flat room-by-room over the next 3 years.
Is the combo package really cheaper than buying separately?
Yes. For BTO: Kitchen Standard (S$11,290) + 2 Toilets Standard (S$9,990) = S$21,280. Combo = S$18,390 — saves S$2,890. For Resale Hacking: Kitchen (S$14,390) + 2 Toilets (S$11,990) = S$26,380. Combo = S$24,990 — saves S$1,390.
Tiles or vinyl for the living area?
For a 4-room flat with 90–95 sqm of floor area, the cost difference is approximately S$2,000–S$2,500. Tiles last 15–20 years, stay cool, and require almost no maintenance. Vinyl installs faster, feels warmer, and suits homeowners who plan to change flooring within 8–12 years.
How long is the whole renovation if I do everything?
For a BTO doing kitchen + toilets + bare unit in one project: approximately 4–5 weeks. For a resale whole-house hacking: 8–10 weeks. Both assume no major public holidays fall within the renovation window.
