Custom Wooden Kitchen Cabinet Depth Measurement: 2025 Expert Guide by MRETTY SG

Introduction: Why Precision in Custom Kitchen Cabinet Depth Matters

In Singapore’s compact homes, every inch of kitchen space counts. A poorly measured cabinet depth can lead to wasted storage, awkward appliance fit, or even structural issues like warping—especially with high-humidity climates. As a leading premium custom wooden kitchen cabinet brand in Singapore, MRETTY has seen firsthand how precise depth measurement transforms functional kitchens into stunning, long-lasting spaces. Whether you’re renovating a HDB flat or a landed property, understanding custom wooden kitchen cabinet depth measurement is non-negotiable for optimal design and durability.

This guide, crafted by MRETTY’s lead designers, breaks down the process, compares industry standards, and showcases real-world success stories—all while highlighting why our ENF-grade OSB, aerospace aluminum honeycomb tech, and E0 finishes make us the top choice for discerning Singapore homeowners.

Step 1: Pre-Measurement Prep – Setting the Foundation for Accuracy

Before reaching for a tape measure, preparation is key. “Most homeowners skip this step and end up with misaligned cabinets,” warns Kenji Tanaka, MRETTY’s head of customization. Here’s what to do:

• Clear the Area: Remove existing clutter, appliances, and old cabinets to expose raw walls and floorings.

• Check Wall Flatness: Use a spirit level to identify uneven surfaces—common in older HDB blocks. Uneven walls require depth adjustments to avoid gaps.

• Note Appliance Specifications: If integrating ovens, dishwashers, or refrigerators, gather their exact dimensions (height, width, depth). For example, a built-in microwave might need 600mm depth clearance, impacting adjacent cabinet design.

MRETTY’s team always conducts a free on-site survey in Singapore, using laser measurers to capture micron-level details. This avoids errors from DIY tools and accounts for Singapore-specific quirks like sloped ceilings in attic conversions.

Step 2: Measuring Key Zones – Water Sink, Stove, and Corner Cabinets

Not all cabinet depths are created equal. Critical zones demand tailored measurements:

a. Sink Base Cabinets

Singaporeans love deep sinks for family meals, but the cabinet depth must accommodate both the sink and plumbing. The standard is 550-600mm, but MRETTY recommends 580mm for most HDB kitchens. Why? Our full-aluminum wrap-around sink bases prevent moisture from seeping into the ENF OSB core—a common issue with thinner, particleboard cabinets.

b. Stove/Oven Cabinets

Range hoods and ovens need 600-650mm depth to allow airflow and easy cleaning. MRETTY’s hidden hinge system adds just 2mm to the recess depth, ensuring sleekness without compromising function.

c. Corner Cabinets

L-shaped kitchens often suffer from “dead space” in corners. MRETTY uses 25mm-thick door panels with J-groove designs to maximize corner access. We measure diagonal depth (700-750mm) to fit pull-out shelves or lazy susans, avoiding the “can’t reach the back” frustration.

Pro Tip: For open-concept kitchens, align upper cabinet depths with lower ones (e.g., 350mm uppers paired with 580mm lowers) for visual harmony—something MRETTY’s designers excel at.

Step 3: Factoring in Hardware & Countertop Overhangs

Hardware and countertops can alter final depth. Here’s what to adjust for:

• Hinges: Traditional exposed hinges add 10-15mm to the recess depth. MRETTY’s concealed hinges sit flush, saving space and reducing dust traps.

• Countertops: Granite or quartz tops typically overhang 20-30mm. Ensure cabinet depth accounts for this—otherwise, the countertop may overhang beyond the cabinet, creating an unpolished look.

• Drawers: Soft-close drawers need 15mm extra depth for smooth operation. MRETTY’s 25mm-thick drawer boxes (vs. industry-standard 18mm) prevent sagging, even with heavy pots.

Step 4: Verifying Opening Sizes & Clearance

Even with precise measurements, gaps or rubbing can occur. MRETTY’s final check involves:

• Door Clearance: 2-3mm gap between doors to prevent sticking in Singapore’s humidity. Our aerospace aluminum honeycomb frames expand minimally, unlike solid wood.

• Side Clearance: 5mm between adjacent cabinets for easy cleaning.

• Top Clearance: 100mm between upper cabinets and ceiling for ventilation and recessed lighting.

Step 5: Finalizing with MRETTY’s Customization Software

Once measurements are locked, MRETTY inputs data into our proprietary 3D design tool. Clients see real-time renders of their kitchen, including depth-adjusted cabinets, material finishes, and soft furnishing mockups. This “try before you build” approach minimizes post-installation regrets—a perk loved by our clients in Orchard and Tampines.

MRETTY vs. Competitors: Why Depth Precision Matters More With Us

Real Case Study: A Tampines HDB Kitchen Transformation

Meet Mrs. Lee, a Tampines resident with a 6 sqm kitchen in a 40-year-old HDB flat. Her main pain points? A cramped layout, frequent cabinet warping from humidity, and a desire for a “Instagram-worthy” space.

The Challenge

Mrs. Lee’s original cabinets were 500mm deep—too shallow for her large pots and pans. The particleboard warped within 2 years, and the exposed hinges collected grime.

MRETTY’s Solution

1. Depth Measurement: We measured 580mm for base cabinets (accommodating her 550mm sink + 30mm plumbing buffer) and 350mm for uppers to match her ceiling height.

2. Material Upgrade: ENF OSB with aerospace aluminum honeycomb cores prevented warping, even during Singapore’s monsoon season.

3. Hardware: Concealed hinges saved 10mm of depth, allowing deeper drawers for her cookware.

4. Aesthetic Touches: J-groove 25mm door panels in oak veneer, paired with a matte white countertop, created a bright, modern look.

The Result

Mrs. Lee now has 30% more usable storage, zero warping after 18 months, and a kitchen featured in MRETTY’s 2024 portfolio. “The precision in depth measurement made all the difference—every inch works!” she shares.
