Bosch 300 Series Compact Dryer: What you need to know

The Bosch 300 Series Compact Dryer is a 24-inch dryer designed to fit small laundry spaces or utility rooms. It is a condensation dryer meaning it has no outside vent and requires no duct, making installation much easier.

Despite its stature, it delivers powerful results that can take on any full-sized dishwasher. Set in a durable unit, it has a 4.0. cu. ft. large capacity drum which is adequate for medium-heavy loads. The large LED display and front controls are simple to use, and add to the sleek appearance. 

It boasts 15 cycles and four drying programs, offering you plenty of choice for customizing your drying needs. It also has convenient options such as a wrinkle block program that significantly reduces creases in clothing, and the moisture sensor prevents over drying and more energy efficient. The automatic dry control helps to ensure each load is evenly dried, before the end-of-cycle signal will notify you once the cycle is completed. 

Generally, the condensate drying system is efficient in delivering results and also eliminates the need for additional ductwork, and you can plug your compatible WAT28402UC, WAT28401UC or WAT28400UC washer (not included) directly into the dryer for simple installation.

 Bosch 300 Series Compact Dryer: Price

There is an assumption that smaller dryers are cheaper than their full-sized counterparts. But if you don’t want to sacrifice quality, then expect to pay the full price. This model is on the premium scale costing $989.10 at the Home Depot. They also offer finance for $165.00 per month. Similarly, it costs $989.99 at Best Buy who also offer finance payments.  It may be costly, but its top performance and space convenience makes it a worthwhile investment.

 Bosch 300 Series Compact Dryer: Features

Even for a smaller dryer, the Bosch 300 Series Compact Dryer has impressive features. It boasts 15 drying cycles that includes, heavy-duty, delicates, jeans, towels, and more.

Dimensions (WHD): 23.5 x 33.25 x 25-inches
Type: Front loader
Capacity: 4.0 cu. ft

Another feature is the moisture sensor that measures moisture in the drum and air temperature. This will then adjust the drying cycle in real-time to save you on energy and ensuring great results. Heating options include a Time Dry and Delay-Start which are handy for when you’re busy on the move.

Its condensation drying system works well to enhance drying performance and quality care of the fabric. Bear in mind that as this does not have an outside vent, you may need sufficient ventilation in your laundry area.

Bosch 300 Series Compact Dryer: Design

Sleek and functional, this model is well engineered to fit into small laundry spaces or stackable with the appropriate kit. It has a top electronic control that makes cycle and option selection nice and simple, and large LED display for remaining time. With a see-through door and white door ring, its modern appeal blends well with any cabinetry.  

While its 4.0 cu. ft capacity may seem small, it is spacious enough for a full load with ample room for around 16 bath towels at once. Overall, it’s easy to maintain, user-friendly and space efficient.

Bosch 300 Series Compact Dryer: Performance

Bosch are renowned for durability, quality and performance. And despite the Bosch 300 Series compact build, it certainly doesn’t compromise on any of those. It has a vast choice of 15 dry cycles, which is more than adequate for busy households.

We particularly liked the moisture sensor function that automatically adjusts the clothes moisture levels with the right drying cycles. And the convenient, wrinkle block program effectively reduces any creasing at the end of each cycle. Saving you on ironing time!  

The condensate system (no vent feature) captures the moisture in a special louver system and retains the warmth inside, which gives a more efficient dry and saves energy.

It is useful to note that since this is ventless, drying cycles can take much longer (around 60 minutes or more). However the end results will not disappoint, and it has the added bonus of being super quiet! 

Bosch 300 Series Compact Dryer: User Reviews

Users reviewers gave this model an average of 4 out of 5 stars with a 73% recommendation on the Home Depot. While 84% of users would recommend on Best Buy, out of 32 reviews.

The majority praised its great drying results, and wide selection of cycles, with one user stating the “dryer exceeds all expectations”. Others liked its compact size, saying it was able to fit well into their confined spaces. The sleek appearance, user-friendly controls and quiet operation were also praised.

The only complaints were that drying times took much longer due to its condensation system, but were still pleased with the overall results.

Should you buy Bosch 300 Series Compact Dryer?

If you have limited space for a standard dryer or run a small household, this Bosch 300 Series Compact Dryer is ideal. Not only does it include 15 cycles and other useful features, but delivers a powerful dry. While cycles do take a little longer, it will leave you with evenly dry, non-static and wrinkle-free clothing.

For families with tons of heavy-duty washing a week, this model is probably not suitable. However, it’s sufficient enough for a couple or small household with minimal requirements.  

At $989.10, it does come at a premium cost. However, the Bosch 300 Series Compact Dryer is a reliable compact dryer that can give full-sized ones a run for their money!
