Is a bottom mounted refrigerator good?
Yes. A bottom-mount refrigerator like the Thermador T36IT71FNS is a great choice when you want everyday fresh-food items at eye level and less bending for the refrigerator section. It is also a strong fit for built-in kitchens when the installation space is properly prepared and level (see the T36IT71FNS installation guide).
- Easier access to fresh food because the refrigerator compartment is on top
- Less frequent bending for daily items (milk, produce, leftovers)
- Better organization for refrigerated foods with shelves and drawers at comfortable height
- A cleaner built-in look in many kitchen layouts
- Good long-term usability for households that cook often
Thermador built-in bottom-mount refrigerators are heavy and need a solid, level installation area. The installation guidance for this model calls out key requirements such as a dry, ventilated room and a properly supported base.
- Install indoors in a dry, ventilated room (avoid areas at risk of frost)
- Keep ambient temperature in the recommended range (about 55 °F to 110 °F)
- Use a grounded 3-prong outlet (no adapter, no extension cord)
- Confirm the cavity is square and the exact size before sliding the unit in
- Secure surrounding cabinetry and overhead fixtures so the appliance can be anchored safely
| Style | Best for | Tradeoffs |
|---|---|---|
| Bottom-mount (bottom freezer) | Daily fresh-food access, less bending for fridge items | Freezer access is lower; built-in installs require careful prep |
| Top-mount (top freezer) | Value and simplicity | More bending for fresh food |
| Side-by-side | Narrow door swing, equal access | Less wide shelf space for platters |
A bottom-mount refrigerator is “good” when it matches how you use your kitchen and when it is installed correctly. With a built-in model like the Thermador T36IT71FNS, proper leveling, support, and electrical setup help prevent door alignment issues, vibration, and cooling performance problems over time.

What are the disadvantages of a bottom freezer?
Bottom-freezer refrigerators like the Thermador T36IT71FNS put fresh food at eye level, but the tradeoff is that frozen items sit lower and are usually stored in deep drawers. That design can mean more bending, heavier lifting, and more digging to find smaller items.
- You often need to bend or squat to access the freezer drawer, which can be tough on backs and knees.
- Large frozen items (roasts, bulk bags, ice) can be awkward to lift up and out.
- Deep baskets can hide smaller packages, so food is easier to lose or forget.
- Freezer drawers can feel heavier when fully loaded and may be harder for kids to manage neatly.
- If the freezer drawer is left ajar, temperatures can rise quickly because of the large opening.
We recommend these practical habits for bottom-mount layouts:
- Use bins or labeled freezer bags to group like items (meat, vegetables, breakfast, etc.).
- Keep frequently used items in the upper basket (if equipped) and bulk items in the lower basket.
- Avoid overfilling; a packed drawer is harder to slide and harder to organize.
- Confirm the drawer closes smoothly and seals fully after every use.
- Follow the clearances, leveling, and door alignment steps in the installation guide so drawers and doors operate correctly.
| Feature | Bottom freezer | Top freezer |
|---|---|---|
| Fresh food access | Easier (less bending) | More bending |
| Frozen food access | More bending | Easier |
| Organization | Deep drawers can bury items | Shelves can be easier to scan |
| Handling heavy items | Harder lift from low drawer | Easier lift from higher shelf |
Most day-to-day refrigerator use happens in the fresh-food section, so bottom-freezer designs can feel convenient. The downside shows up when you rely heavily on frozen storage or want quick visibility of everything in the freezer. For model-specific use and care tips, use the owner's manual.

What is the life expectancy of a bottom freezer refrigerator?
Most bottom freezer (bottom-mount) refrigerators last 15 years. With consistent care (clean airflow paths, good door sealing, correct temperatures), a Thermador bottom-mount like T36IT71FNS reaches that full service life more reliably.
- Condenser airflow and cleanliness (dust buildup makes the compressor work harder)
- Door seal condition and alignment (warm air leaks increase run time)
- Stable electrical supply (proper grounded outlet, no extension cords)
- Proper installation support and leveling (reduces stress on doors and cabinet)
- Water system maintenance (filter changes help protect valves and the ice maker)
| Task | How often | What it helps prevent |
|---|---|---|
| Clean condenser area and ensure airflow | Every 6 months | Overheating, long run times, compressor wear |
| Check door gaskets for gaps and wipe clean | Monthly | Frost, moisture, temperature swings |
| Replace water filter (if equipped) | Every 6 months | Slow water flow, bad taste, valve strain |
| Confirm temps (fresh food and freezer) | Monthly | Food spoilage, excessive cycling |
Your Thermador T36IT71FNS is a heavy built-in design; the installation guide emphasizes a flat, level, load-bearing base and proper electrical grounding. Those basics matter because poor support or power can shorten the life of major components like the compressor and start relay. See the T36IT71FNS installation guide for the installation requirements and electrical details.
A refrigerator’s most expensive wear items are the sealed-system components (compressor, evaporator) and airflow parts (fans). Keeping airflow clear and doors sealing tight reduces run time, which directly reduces wear and extends service life.
If you are maintaining the water system, use the correct filter for this model, such as the refrigerator water filter 11034152.
