2017-2023 Discovery Trunk Storage Box: Fitment Guide for 5-Seat vs. 7-Seat Models
This guide explains the critical differences in the trunk floor storage box between 5-seat and 7-seat Land Rover Discovery models to ensure you buy the correct part.
- The single most important factor is vehicle seating: the storage box for a 5-seat Discovery is completely different and not interchangeable with a 7-seat model.
- Failure is always physical damage like cracks or warping; this part will not cause any mechanical or electrical issues.
- Installation is extremely easy and requires no tools, making it a perfect DIY job that takes less than 10 minutes.
- A used OEM part is a cost-effective choice, but you must verify it came from a vehicle with the same seating configuration as yours.
Compatibility: The Most Important Check
When replacing the trunk floor storage box on a 2017-2023 Land Rover Discovery, one factor is more important than any other: your vehicle's seating configuration. The cargo area is significantly different between models equipped with two rows of seats (5-passenger) and those with three rows (7-passenger).
Warning: The storage boxes for 5-seat and 7-seat models are not interchangeable. A box from a 5-seater will not fit in a 7-seater, and vice-versa. The floor pan and mounting points are different.
5-Seat vs. 7-Seat Models
The key difference is what lies beneath the main cargo floor. In 7-seat models, the third-row seats fold down into a well in the floor. This leaves very little room for any additional storage tray. In 5-seat models, this well is empty, allowing for a large, deep storage box to be fitted. This provides a significant amount of hidden storage. Before purchasing, you must confirm if your Discovery is a 5-seat or 7-seat version.
2021 Model Year Refresh
The Land Rover Discovery received a model refresh for the 2021 model year, which included updated styling, new engines, and interior technology enhancements. While the exterior and center console were redesigned, the fundamental structure of the rear cargo area and seating configurations remained largely the same. The storage box part numbers appear to cover the full 2017-2023 range, suggesting the part did not change. However, it is always best to verify compatibility by comparing photos of the replacement part with your original part.
Symptoms of a Damaged Trunk Floor Storage Box
As a non-mechanical part, failure is purely physical. There are no codes or drivability issues associated with it. Symptoms are visible and include:
- Cracks or Breaks: Heavy or sharp objects dropped into the bin can cause the plastic to crack or shatter.
- Warping: Extreme heat or storing heavy items for long periods can cause the box to lose its shape, leading to a poor fit.
- Broken Mounting Points: If the box is secured with tabs or clips, these can break during removal or from rough use, causing the box to rattle or shift.
- Stains or Odors: Spills from chemicals, oils, or other liquids can permanently stain the plastic and leave lingering odors.
Buying a Used Trunk Floor Storage Box: What to Check
This is an excellent part to buy used, as a good condition recycled OEM part is functionally identical to a new one. Here’s what to inspect:
- Confirm the Donor Vehicle's Seating: This is the most critical step. Get the Vehicle Identification Number (VIN) of the vehicle the part came from and have a Land Rover dealer or parts specialist confirm if it was a 5-seat or 7-seat model. Do not rely on visual estimation alone.
- Inspect for Cracks: Carefully check the entire box, especially the corners, bottom, and any load-bearing ridges, for hairline cracks or stress marks.
- Check for Warping: Place the box on a flat surface. It should sit flush without any significant rocking or bowing. Check that the upper edges are straight.
- Verify All Components are Present: Some versions may come with removable dividers or lids. Ensure all pieces are included with the used part.
- Look for Chemical Damage: Check for discoloration, soft spots, or a brittle texture that could indicate damage from spilled chemicals like solvents or battery acid.
Installation Guide
Replacing the trunk floor storage box is a simple, tool-free process.
- Difficulty: 1 out of 5
- Time: Less than 10 minutes

Steps:
- Open the tailgate.
- Lift up and remove the main cargo floor panel (the carpeted board) to expose the storage area beneath.

Frequently Asked Questions (FAQ)
Will the storage box from a 7-seat Discovery fit in my 5-seat model?
No. The 7-seat model has almost no under-floor storage because the space is occupied by the folded seats. The 5-seat model has a large, deep well where the seats would have been, which is where this storage box fits. The parts are not interchangeable.
Is this part the same as the spare tire cover?
No. This storage box sits above the spare tire well. You must remove this storage box and often another layer of trim to access the spare tire from inside the vehicle.
Can a cracked storage box be repaired?
While it is sometimes possible to repair cracked plastic using plastic welding techniques or strong epoxies, it is generally not recommended for this part. A repair may not be strong enough to hold heavy items, and given the reasonable cost of a used replacement, replacing the entire unit is the more reliable solution.
Are there aftermarket storage solutions available?
Yes, there are many generic and custom-fit aftermarket cargo organizers, including modular panel systems and storage bags. However, the OEM trunk floor storage box is specifically molded to fit the contours of the vehicle floor for a perfect, rattle-free fit, which aftermarket solutions may not provide.
