On page 92 and 93 of Zubrin's book, The Case For Mars, he gives specific mass estimates for each component of his proposed Mars Direct Mission. These figures are widely disputed, and are given together as a whole here.

Figures Suggested by Zubrin
Hab
Total Mass: 25.2 Tonnes
- Hab Structure: 5.0 Tonnes
- Life Support System: 3.0 Tonnes
- Consumables: 7.0 Tonnes consisting of (TCFM page 92):
- Oxygen: 160 kg total (1 kg/man*day at 80% reuse)
- Dry Food: 1600 kg total (.5 kg/man*day at 0% reuse)
- Whole Food: 3200 kg total (1 kg/man*day at 0% reuse)
- Potable Water: 0 kg total [?] (4 kg/man*day at 80% reuse)
- Wash Water: 2080 kg total (26 kg/man*day at 90% reuse)
- Electric Power (5 kWe solar): 1 tonne
- Reaction Control System: .5 tonnes
- Communications and information management: .2 tonnes
- Lab Equipment: .5 tonnes
- Crew: .4 tonnes
- EVA Suits (4): .4 tonnes
- Furniture and Interior: 1 tonne
- Open Rovers (2): .8 tonnes
- Pressurized Rover: 1.4 tonnes
- Field Science Equipment: .5 tonnes
- Spares and Margin (16%): 3.5 tonnes
ERV (Earth Return Vehicle)
Total Mass: 28.6 Tonnes
- ERV Cabin Total: 11.5 Tonnes
- ERV cabin structure: 3.0 tonnes
- Life support System: 1.0 tonnes
- Consumables: 3.4 tonnes
- Electrical Power (5 kWe Solar) 1.0 tonnes
- Reaction Control System: .5 tonnes
- Communications and Information Management: .1 tonne
- Furniture and Interior: .5 tonnes
- EVA suits (4): .4 tonnes
- Spares and Margin (16%): 1.6 tonnes
- Aeroshell: 1.8 tonnes
- Light Truck: .5 Tonnes
- Hydrogen Feedstock: 6.3 Tonnes
- ERV Propulsion Stages: 4.5 tonnes
- Propellant Production Plant: .5 tonnes
- Power Reactor (80 kWe): 3.5 tonnes
Figures Estimated as a part of the Tsiolkovsky Compendium Project
Note that if these are empty, it means that they have yet to be addressed by Tracers or final estimated masses determined. All items should have not only the estimated mass, but also what this mass is compared to the masses suggested by Zubrin and reproduced above.
