Recently I renovated my master bath and kid's bathroom with the help of Bonnie. I literally met with 6 different designers before hiring her. What I appreciated most about her was that she was transparent in her opinions and seemed very 'real'...unlike other stuffy designers. I came into the project with a lot of inspiration already...that scared others off...not Bonnie.. Not to mention, I wanted to interview and hire my own contractor. Other designers prefer that you work with their preferred contractor (likely because they get a cut), but again, Bonnie gave me that flexibility. If you've ever remodeled a bathroom or kitchen, you know there are millions of little decisions to be made…… More than anything, I needed someone to get the ball rolling for me and be there to answer questions throughout the 2 months of construction.. I think Bonnie's greatest strength is her communication. No matter the time of day,   I always had an answer almost immediately. Given how stressful all this can be, her communication really helped ease the process. That by itself was worth it's weight in gold.

I have had an amazing experience working with Bonnie Bagley Catlin from Signature Designs. I first found her on Houzz.com. I had just purchased a condo in Solana Beach, and wanted to remodel it in a contemporary style. Bonnie is highly talented, professional, and worked very hard to find value throughout the remodeling process. She was willing to listen to my ideas, but also pushed the project in some exciting directions I would not have imagined on my own. She worked very well with the contractor that she helped me find. “I think that is one of your greatest talents. Encouraging people to go out of their comfort zone into something amazing! Great effect.”

I loved working with Bonnie. She entered our home to meet for the first time and immediately gave us so many great suggestions before we even hired her. Her ideas are beautiful and she listens to our desires, as well. She was always available to help and responded immediately when I needed her. I would highly recommend Bonnie.

Bonnie truly made our kitchen and bath remodel possible. They walked us through every step of the design process, presenting options and really listening to what we wanted to achieve. Before Bonnie, any steps towards remodel felt overwhelming and ended at a dead end. After Bonnie, we have beautiful new spaces that we love. I'd love to work together again any time!

We are extremely happy with our new kitchen and would highly recommend working with Bonnie. She is very organized, listened to our design ideas, made solid recommendations and is very knowledgeable in all aspects of design and construction. Bonnie also has a phenomenal group of contractors, and suppliers which made the material selection and installation go smoothly. We initially wanted to redo our island and paint out our existing cabinets, we are very glad we made the bigger investment, as it was well worth it. It feels like we live in a new house now, and we didn't have to move!

We did a complete kitchen remodel and used Signature Designs Kitchen Bath assist us with the kitchen design and cabinet choice. Bonnie listened carefully to our list of wishes and must haves for our space. Bonnie preplanning saved us some potentially costly structural issues we could have had if we did the design we had originally envisioned. She did a wonderful job designing a functional kitchen that is a pleasure to cook & entertain in while working around some structural restraints.
Our kitchen design expanded our countertops space and the new kitchen design has improved the function for our young family. I was nervous but it works beautifully! We have so much storage now with the conveniences that make cooking easier. We highly recommend Bonnie at Signature Designs Kitchen Bath

Bonnie has a unique ability that sets her apart from any other designer we have worked with. She combines her creativity and her clients practical needs with impeccable project management, making her an asset on any design concept. When we met Bonnie, we knew we were going to completely remodel our kitchen, but unfortunately that was all we knew. She was able to look at our existing kitchen and propose ideas that truly fit with who we are and how we would realistically get the best use of the space. Bonnie is able to communicate her vision beautifully and was able to know what we wanted even better than we did. She made our kitchen an absolute dream that we could never have envisioned ourselves. 

Bonnie has a wide range of talents and is not boxed in by one design technique. She truly makes the effort to get to know you and your needs in order to create the best version of your vision. She was present to guide us every step of the way, as well as oversee our contractor and vendors. Her attention to detail, strong problem solving strategies, and high standards ensured we completed our kitchen on time and with the highest quality. We have already recommended Bonnie to several people and will continue to do so. We look forward to conquering other rooms with full confidence.

We have been enjoying our stunning new kitchen for one year now, and will be forever grateful to Bonnie for making it a reality!  The layout of our home limited the options available when we decided to renovate our second floor kitchen. Bonnie’s brilliant idea was to slightly re-route the stairs which immediately gave us a more workable space. She then designed the room to take full advantage of our ocean views. Bonnie guided us through the process of selecting cabinets, flooring, fixtures, appliances, paint, fabrics, furniture, tile and more. She has an eye for color and materials and offered many creative suggestions which turned out to be spot on. When I found paint or tile that I wanted to use, she somehow found the perfect place or way to incorporate them. When she purchased décor and staged the rooms for photos (another service she provides), we loved what she used so much we kept almost everything she bought. Bonnie worked flawlessly with our General Contractor to anticipate and quickly resolve issues as they arose. She is an excellent communicator and was responsive and available throughout the entire project. I recommend Bonnie to anyone looking for both creative solutions and the professionalism to guide the project through to completion.

Bonnie is responsive, efficient, has amazing taste and so great to work with. I was out of the country during the majority of our first floor renovation (kitchen, dining, living room and powder room) and Bonnie was amazing. We were able to communicate and make all the decision over email or facetime. My husband and I are the type that know what we like and don't like when we see it but to choose from the millions of options for tile, handles, mirrors, light fixtures, counter tops, etc. - forget it. Having Bonnie was an incredible time-saver, she listened to what we wanted, provided feedback to our ideas, gave us options that fit our needs, and offered decor ideas we would have never thought of on our own. In the end, we have an AMAZING space that love to call home. Thank you Bonnie! We love our home!

Bonnie helped us with a complete redo of our kitchen and Powder Room. We also replaced an out-dated fireplace, added new flooring and created a doorway to the exterior deck. Her idea to install French doors to replace an old window seat created a more efficient use of space.  Our kitchen, beautiful and updated, has more storage and counter space. Our Powder Room has better flow due to moving a wall and enclosing the toilet.  We are most appreciative of Bonnie's eye for design, color and blending of textures and materials. We are so pleased with the results! - Marti and Pat McC.

My wife and I hired Bonnie to design a master bath/master bedroom and living room remodel. We loved Bonnie from the moment we met her. Bonnie took the time to listen to exactly what my wife and I were looking for. Bonnie was able to adapt to our style which was extremely important to us. We didn't want to hire someone that pushed their own design. We wanted to be part of the process.. Our master bed and bath came out much nicer then we expected. Bonnie works quick and efficiently...We can't wait to use Bonnie on our next project. Strongly recommended!

I live in N. CA, and Bonnie is in S. CA, so she did not design our kitchen; however, we worked with her to purchase items for our remodel. We received great customer service. We ordered the incorrect item initially, and Bonnie quickly gave us feedback and found a way to remedy the problem. As well, she helped us expedite the shipping and return. We would definitely work with her again.  Thank you Bonnie!

I cannot stress enough how pleased I am with the quality of work I received from Bonnie. I met her at a kitchen event. My husband and I were in the initial phase of remodeling our kitchen, laundry room and bath. We basically had no idea what we were doing. Bonnie came to our house measured our kitchen, laundry room and bath. They were all blank shells and she was able to design a kitchen, bath and laundry room layout that was functional and beautiful. In addition, our contractor suggested we go to a big store to get the cabinet, the layout they did was not satisfactory, and was way expensive. The same cabinets that the big store quoted us for the kitchen only cost more than the exact same cabinets Bonnie got us for the kitchen, laundry room and bathroom. Even though our remodel took a very long time, contractor was slow, Bonnie was still available to us until the end. There was an issue with a drawer and Bonnie took care of it 9 months after we ordered the cabinets. I would hire her again in a minute and if I did not already have an interior designer hired, I would have had her as our interior designer too.

Bonnie's design services have been invaluable for our kitchen remodel. From our very first meeting with Bonnie, we were extremely impressed with Bonnie's ability to translate our vision for the space into a reality. Bonnie has an incredible eye for design and thinks of the smallest detail to enhance your space. Throughout our project, Bonnie has continued to keep in contact with us ensuring that if we need any assistance, she would be available. While it has taken a few months on our end to make final selections, Bonnie has stuck with us the entire time taking calls and emails from us anytime/anywhere to assist us wherever needed. We cannot thank Bonnie enough for all she has done and cannot wait to see our kitchen come to life. If you are seeking design services for your home, we cannot recommend Bonnie enough - she is the best in the business!

Bonnie has a great eye for color, shapes and textures. She is in tune with current trends in design, and she has a knack for adapting these trends to the needs of the client. She helped create designs for our bathrooms incorporating unusual stones, tiles and layouts that has completely transformed the spaces and made them pop. She did a similarly good job with her design suggestions for our Master Bedroom renovation. I would recommend her services highly.

Bonnie is a very good designer, patient, and helpful in several ways. She understood what we needed from the start, came up with interesting ideas, and even planned out my lighting in less than 15 minutes. She emailed pictures of appliances, other kitchens, design ideas, lighting ideas and helped us select countertops and cabinets. She is patient. Four designs and five months later we are still undecided what to do in the kitchen. At this point we have decided to pay her hourly. Throughout a family illness, religious holidays, a broken drain pipe under the foundation, a steady stream of summertime relatives, and the complication of a kosher kitchen, Bonnie kept up with our changes and answered my phone calls promptly, even after long delays on my part. She was very helpful. She created a powder room layout, and helped me decide on paint color for our fireplace without an extra fee. I was inspired to change some minor structures in our kitchen and she referred me to several contractors, plumbers, and electricians as well as giving aesthetic advice on what opening or wall should stay and what should go. I also liked that she was ok to settle on a fee for her design work up front without obligation to buy from her vendors. She used a color computer rendering only on the first design and allotted one hour for site visits. I think we met at least 6-7 times. The only downside was that although cabinet measurements and appliance placements were well defined, I needed more details to understand where my stuff would go in the designs and, besides the first computer rendering, a clearer picture of how our kitchen would look. For people who want fun and innovative ideas, who are quick to know what they want and who rely on architects and contractors for detail, she is phenomenal.
